feat: admin secrets provisioning API + API documentation

- Add PUT/GET/DELETE /api/admin/users/{id}/secrets/{name} endpoints for application backends to provision per-user secrets (AES-256-GCM encrypted) - Add secrets_store field to GatewayState with builder wiring - Create docs/USER_MANAGEMENT_API.md with full API spec covering users, secrets, tokens, profile, and usage endpoints - Update web gateway CLAUDE.md route table Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>

+## 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) |

+  "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.
+```
+

+
+### GET /api/admin/users/{user_id}/secrets
+
+List a user's secrets. Returns names and providers only — **never values or hashes**.

+  ]

+
+Delete a specific secret for a user.

+## 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
