feat(frontend): hash-based URL navigation for page refresh persistence

Navigation state is now encoded in window.location.hash so refreshing the page (or sharing a URL) restores the current view: #/chat → chat tab, assistant thread #/chat/{threadId} → specific conversation #/memory/{path/to/file} → memory browser with file open #/jobs/{jobId} → job detail view #/routines/{id} → routine detail view #/settings/{subtab} → settings sub-tab (extensions, etc.) #/logs → logs tab Hooked into all navigation functions: switchTab, switchThread, switchToAssistant, createNewThread, readMemoryFile, openJobDetail, closeJobDetail, openRoutineDetail, closeRoutineDetail, switchSettingsSubtab. Thread restore is deferred until loadThreads() completes (async), then the pending thread ID is matched against the loaded thread list. Browser back/forward buttons work via hashchange listener.

 # User Management API
 DB-backed user management for multi-tenant IronClaw deployments. Covers admin user CRUD, per-user secrets provisioning, self-service profile, API token management, and usage reporting.
 ## Authentication
 All endpoints require `Authorization: Bearer <token>`. Tokens are either:
 - **Env-var tokens** — configured via `GATEWAY_AUTH_TOKEN` (single-user) at startup
 - **DB-backed tokens** — created via `POST /api/tokens` or `POST /api/admin/users`
 DB tokens are SHA-256 hashed at rest; plaintext is returned exactly once at creation time.
 Auth is cached in a bounded LRU (1024 entries, 60s TTL). Suspending a user or revoking a token may take up to 60s to take effect.
 ## Roles
 | Role | Scope |
 |------|-------|
 | `admin` | Full access to all endpoints |
 | `member` | Self-service profile + own token management only |
 Endpoints marked **Admin** return `403 Forbidden` for `member` role.
 ---
 ## Admin: Users
 ### POST /api/admin/users
 Create a new user. Returns the user record and a one-time plaintext API token.
 **Auth:** Admin
 **Request body:**
 ```json
 {
  "display_name": "Alice Smith",
  "email": "[email protected]",
  "role": "member"
 }
 ```
 | Field | Type | Required | Default | Notes |
 |-------|------|----------|---------|-------|
 | `display_name` | string | yes | | |
 | `email` | string | no | `null` | Must be unique if provided |
 | `role` | string | no | `"member"` | `"admin"` or `"member"` |
 **Response:** `200 OK`
 ```json
 {
  "id": "550e8400-e29b-41d4-a716-446655440000",
  "email": "[email protected]",
  "display_name": "Alice Smith",
  "status": "active",
  "role": "member",
  "token": "a1b2c3d4e5f6...64-char hex...",
  "created_at": "2026-03-25T12:00:00+00:00",
  "created_by": "admin-user-id"
 }
 ```
 The `token` field is the plaintext API token. It is shown **only once** — store it securely.
 **Errors:** `400` (missing display_name, invalid role), `403` (not admin), `503` (no database)
 ---
 ### GET /api/admin/users
 List all users.
 **Auth:** Admin
 **Response:** `200 OK`
 ```json
 {
  "users": [
    {
      "id": "550e8400-...",
      "email": "[email protected]",
      "display_name": "Alice Smith",
      "status": "active",
      "role": "member",
      "created_at": "2026-03-25T12:00:00+00:00",
      "updated_at": "2026-03-25T12:00:00+00:00",
      "last_login_at": "2026-03-25T14:30:00+00:00",
      "created_by": "admin-user-id"
    }
  ]
 }
 ```
 ---
 ### GET /api/admin/users/{id}
 Get a single user by ID.
 **Auth:** Admin
 **Response:** `200 OK`
 ```json
 {
  "id": "550e8400-...",
  "email": "[email protected]",
  "display_name": "Alice Smith",
  "status": "active",
  "role": "member",
  "created_at": "2026-03-25T12:00:00+00:00",
  "updated_at": "2026-03-25T12:00:00+00:00",
  "last_login_at": "2026-03-25T14:30:00+00:00",
  "created_by": "admin-user-id",
  "metadata": {}
 }
 ```
 **Errors:** `404` (user not found), `403` (not admin)
 ---
 ### PATCH /api/admin/users/{id}
 Update a user's display name and/or metadata. Omitted fields are left unchanged.
 **Auth:** Admin
 **Request body:**
 ```json
 {
  "display_name": "Alice Johnson",
  "metadata": {"department": "engineering"}
 }
 ```
 | Field | Type | Required | Notes |
 |-------|------|----------|-------|
 | `display_name` | string | no | |
 | `role` | string | no | `"admin"` or `"member"` |
 | `metadata` | object | no | Replaces entire metadata object (full replacement; keys not included are removed) |
 **Response:** `200 OK` — returns the full updated user record (same shape as GET detail, without `last_login_at`/`created_by`).
 **Errors:** `404` (user not found), `403` (not admin)
 ---
 ### POST /api/admin/users/{id}/suspend
 Suspend a user. Suspended users cannot authenticate (DB auth checks user status).
 **Auth:** Admin
 **Response:** `200 OK`
 ```json
 {
  "id": "550e8400-...",
  "status": "suspended"
 }
 ```
 **Errors:** `404` (user not found), `403` (not admin)
 ---
 ### POST /api/admin/users/{id}/activate
 Re-activate a suspended user.
 **Auth:** Admin
 **Response:** `200 OK`
 ```json
 {
  "id": "550e8400-...",
  "status": "active"
 }
 ```
 **Errors:** `404` (user not found), `403` (not admin)
 ---
 ### DELETE /api/admin/users/{id}
 Permanently delete a user and all associated data (tokens, jobs, conversations, memory, routines, settings, secrets).
 **Auth:** Admin
 **Response:** `200 OK`
 ```json
 {
  "id": "550e8400-...",
  "deleted": true
 }
 ```
 **Errors:** `404` (user not found), `403` (not admin)
 **Cascade:** Deletes from `api_tokens`, `agent_jobs`, `conversations`, `memory_documents`, `routines`, `secrets`, `settings`, `wasm_tools`, and related tables. On PostgreSQL this uses FK cascades; on libSQL it uses explicit deletes.
 ---
 ## Admin: Per-User Secrets
 Provision secrets on behalf of individual users. The primary use case is an application backend (acting as admin) that configures per-user credentials so each user's IronClaw agent can call back to external services.
 Secrets are encrypted at rest with AES-256-GCM using a per-secret HKDF-derived key. Plaintext values are **never returned** by any endpoint — they can only be used by the agent's tool system at runtime.
 ### PUT /api/admin/users/{user_id}/secrets/{name}
 Create or update a secret for the specified user. If a secret with the same name already exists, it is overwritten.
 **Auth:** Admin
 **Path parameters:**
 | Param | Type | Notes |
 |-------|------|-------|
 | `user_id` | string | The user's ID |
 | `name` | string | Secret name (normalized to lowercase) |
 **Request body:**
 ```json
 {
  "value": "sk-live-abc123...",
  "provider": "my-app-backend",
  "expires_in_days": 90
 }
 ```
 | Field | Type | Required | Notes |
 |-------|------|----------|-------|
 | `value` | string | yes | The secret value (encrypted at rest, never returned) |
 | `provider` | string | no | Tag for grouping (e.g. `"stripe"`, `"my-app"`) |
 | `expires_in_days` | integer | no | Auto-expire after N days; `null` = never |
 **Response:** `200 OK`
 ```json
 {
  "user_id": "550e8400-...",
  "name": "my_app_callback_token",
  "status": "created"
 }
 ```
 **Errors:** `400` (missing value), `403` (not admin), `503` (secrets store not available)
 **Example — application backend provisioning a callback token:**
 ```bash
 # Admin creates a user
 curl -X POST https://ironclaw.example.com/api/admin/users \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"display_name": "Alice", "role": "member"}'
 # Response includes: {"id": "alice-uuid", "token": "alice-bearer-token", ...}
 # Admin provisions a per-user callback secret
 curl -X PUT https://ironclaw.example.com/api/admin/users/alice-uuid/secrets/app_callback_token \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"value": "per-user-jwt-for-alice", "provider": "my-app"}'
 # Now Alice's IronClaw agent can use the "app_callback_token" secret
 # when calling tools that need to authenticate back to the app backend.
 ```
 ---

 ---
 ## Error Format
 All error responses return a plain text body with the error message and the corresponding HTTP status code:
 | Code | Meaning |
 |------|---------|
 | `400` | Bad request (missing fields, invalid input) |
 | `401` | Missing or invalid bearer token |
 | `403` | Authenticated but insufficient role (member accessing admin endpoint) |
 | `404` | Resource not found |
 | `503` | Database or secrets store not available |
 | `500` | Internal server error |
 ---
 ## Security Model
 ### Secrets Encryption
 - **Algorithm:** AES-256-GCM with per-secret HKDF-SHA256 derived keys
 - **Master key:** 32+ bytes, resolved from `SECRETS_MASTER_KEY` env var or OS keychain
 - **Storage format:** `nonce (12B) || ciphertext || tag (16B)` in `encrypted_value` column
 - **Per-secret salt:** 32 random bytes stored alongside the ciphertext
 - **Zero-exposure:** Plaintext never appears in logs, debug output, API responses, or LLM conversations
 ### Auth Cache
 - Bounded LRU cache (1024 entries max)
 - 60-second TTL per entry
 - Suspending a user or revoking a token takes up to 60s to propagate

 # WeChat Integration Design
 **Date:** 2026-03-25
 **Status:** Ready for implementation
 **Goal:** Add WeChat support to IronClaw using the same upstream iLink Bot protocol as `@tencent-weixin/openclaw-weixin`, while keeping the implementation aligned with IronClaw's extension-first channel architecture.
 ---
 ## Upstream Baseline
 The current upstream npm package is `@tencent-weixin/openclaw-weixin` version `2.0.1`.
 From the package README and source, the upstream WeChat channel does all of the following:
 - logs in by QR code against `https://ilinkai.weixin.qq.com`
 - receives inbound messages by long-polling `ilink/bot/getupdates`
 - sends outbound messages through `ilink/bot/sendmessage`
 - uses `ilink/bot/getconfig` and `ilink/bot/sendtyping` for typing indicators
 - uses `ilink/bot/getuploadurl` for media uploads
 - persists `get_updates_buf` for long-poll resume
 - persists `context_token` so replies stay attached to the right WeChat session
 - supports multiple logged-in WeChat bot accounts
 - treats WeChat as a direct-message-only channel
 - block-sends replies instead of token streaming
 This design treats that upstream behavior as the capability boundary. We should not add scope based on features the upstream plugin does not have.
 ---
 ## Implementation Direction
 IronClaw should **not** try to load the upstream OpenClaw plugin directly.
 Instead, IronClaw should implement a **native channel extension** under `channels-src/wechat/` and only extend the host/runtime where that support is generic and reusable.
 ### Why not host the npm plugin directly
 - The upstream package depends on `openclaw/plugin-sdk/*` APIs and runtime contracts that IronClaw does not have.
 - It assumes OpenClaw-specific lifecycle concepts such as `gateway.startAccount`.
 - Recreating an OpenClaw-compatible Node plugin host inside IronClaw would be more work and more fragile than implementing the protocol directly.
 ### Why `channels-src/wechat/`
 - It matches the existing layering used by other platform channels.
 - It keeps platform protocol logic out of host-owned core modules.
 - It leaves room for the channel to move outside this repo later without changing the host model.
 Recommended layout:
 ```text
 channels-src/
  wechat/
    Cargo.toml
    build.sh
    wechat.capabilities.json
    src/
      lib.rs
      api.rs
      auth.rs
      state.rs
      types.rs
 ```
 ---
 ## Phase 1 Scope
 Phase 1 is a **single-account** implementation of the upstream WeChat channel.
 The point of this phase is to keep the channel aligned with upstream behavior while removing the one biggest source of host/runtime complexity: multi-account lifecycle.
 ### Must-have in Phase 1
 - QR code login
 - one connected WeChat bot account
 - direct-message text receive/send
 - `getupdates` long-poll loop
 - `sendmessage` outbound replies
 - typing indicators via `getconfig` and `sendtyping`
 - inbound image download/decrypt for vision
 - outbound image upload/send via `getuploadurl`
 - `context_token` persistence
 - `get_updates_buf` persistence
 - login persistence across restart
 - extension-first packaging under `channels-src/wechat/`
 ### Explicit simplification from upstream
 - multi-account support is deferred
 ### Follow-up after Phase 1
 These are upstream features, so they belong on the roadmap, but they do not need to block the first implementation cut:
 - broader media parity beyond the current image + inbound-file + inbound-voice path (outbound files and video)
 We should not spend time listing non-goals that come from outside the upstream capability boundary.
 ---
 ## Proposed Architecture
 ```mermaid
 flowchart LR
    A["Core WASM channel host"] --> B["WeChat channel extension"]
    C["Generic login UI/API"] --> D["QR login session"]
    D --> E["Secret storage"]
    E --> B
    B --> F["getupdates long-poll"]
    F --> G["IncomingMessage"]
    G --> H["ChannelManager -> Agent"]
    H --> I["sendmessage reply"]
 ```
 ### Extension responsibilities
 `channels-src/wechat/` should own:
 - iLink API request/response types
 - QR login protocol calls
 - long-polling `getupdates`
 - `context_token` storage and lookup
 - outbound `sendmessage`
 - WeChat-specific status/error mapping
 ### Host responsibilities
 IronClaw core should only own reusable pieces:
 - installing and activating the WASM channel
 - generic secret persistence
 - generic QR/device-login session handling for channels
 - exposing login flow through authenticated UI/API
 - starting and polling the channel runtime
 ---
 ## Data And State Model
 Phase 1 is single-account, so state should stay simple.
 ### Secrets
 - `wechat_bot_token`
 This is written after QR login succeeds and reused on restart.
 ### Channel state
 Under the channel workspace prefix, persist:
 - `state/get_updates_buf.json`
 - `state/context_tokens.json`
 `context_tokens.json` maps the WeChat peer to its latest `context_token`.
 ### Inbound message mapping
 For each inbound WeChat DM:
 - `channel = "wechat"`
 - `user_id = <wechat sender id>` or owner scope if it is the bound owner
 - `thread_id = Some("wechat:<sender_id>")`
 - `conversation_scope_id = Some("wechat:<sender_id>")`
 `metadata_json` should include:
 - `from_user_id`
 - `to_user_id`
 - `message_id`
 - `context_token`
 That is enough for `on_respond()` to send the reply back to the right peer.
 ---
 ## Minimal Host Uplift
 The current extension host is close, but Phase 1 still needs one important addition: a generic interactive login flow for channels.
 Minimum host support needed:
 1. Start a channel login session.
 2. Return QR payload plus a session identifier.
 3. Poll login session status.
 4. On success, write the returned token to channel secrets.
 5. Reload or reactivate the channel so polling starts automatically.
 This should be added as a generic channel-auth capability, not as WeChat-specific core logic.
 ---
 ## User Flow
 Phase 1 should be **web-first**, because the target user is a normal WeChat user rather than a CLI-only operator.
 1. Install or enable the `wechat` channel extension.
 2. Click "Connect WeChat".
 3. Web UI requests a login session from the host.
 4. Web UI displays the QR code.
 5. User scans and confirms on their phone.
 6. Host stores `wechat_bot_token`.
 7. Channel reloads and starts polling.
 8. User sends a DM in WeChat and receives IronClaw replies there.
 CLI support can still exist for development, but it should not be the primary Phase 1 UX.
 ---
 ## Message Handling Semantics
 ### Inbound
 On each poll:
 1. load `get_updates_buf`
 2. call `getupdates`
 3. persist the new cursor if present
 4. normalize inbound text messages into `IncomingMessage`
 5. persist the latest `context_token` for that peer
 6. emit the message to the agent
 ### Outbound
 On response:
 1. read peer routing info from `metadata_json`
 2. load the latest `context_token`
 3. convert the response to plain text if needed
 4. send one coalesced text reply via `sendmessage`
 This matches the upstream channel's block-send behavior.
 ---
 ## Testing Plan
 ### Unit tests
 - QR login response parsing
 - `get_updates_buf` round-trip
 - `context_token` round-trip
 - inbound message normalization
 - outbound metadata routing
 ### Integration tests
 Use a mock iLink server to cover:
 - QR login success and expiry
 - restart without re-login
 - inbound poll -> agent -> outbound text reply
 - cursor resume after restart
 ---
 ## Phase 2
 After Phase 1 is stable, add the upstream features we intentionally deferred:
 - multi-account support
 - media upload/send
