feat: persist user_id in save_job and expose job_id on routine runs (#709)

* feat: persist worker events to DB and fix activity tab rendering

In-process Worker (used by Scheduler::dispatch_job) now persists events
via save_job_event at key execution points: plan creation, LLM
responses, tool_use, tool_result, and job completion/failure/stuck.
Event data shapes match the container worker format so the gateway
activity tab renders them correctly.

Frontend: tool_result errors now show a red X icon with danger styling
instead of a silent empty output. The result event falls back to the
error field when message is absent.

* feat: wire RoutineEngine into gateway for direct manual trigger firing

Replace the message-channel hack in routines_trigger_handler with a
direct call to RoutineEngine::fire_manual(), ensuring FullJob routines
dispatch correctly when triggered from the web UI. Inject the engine
into GatewayState from Agent::run after construction.

Also persists user_id in save_job for both PG and libSQL backends,
removes the source='sandbox' filter so all jobs are visible, and
exposes job_id on RoutineRunInfo for the frontend job link.

* fix: remove stale gateway_state argument from Agent::new test call sites

The gateway_state parameter was removed from Agent::new during rebase
(replaced by post-construction set_routine_engine_slot), but three test
call sites still passed the extra None argument.

* fix: address PR review — restore sandbox source filter, remove blank lines

- Revert removal of `source = 'sandbox'` filter in all SandboxStore
  queries (8 sites across PG and libSQL). Sandbox-specific APIs should
  stay scoped to sandbox jobs; unified job listing for the Jobs tab
  should use a separate query path.
- Remove extra blank lines in agent_loop.rs and worker.rs that caused
  formatting CI failure.

* fix: address review — regenerate Cargo.lock, add user_id regression test

- Regenerate Cargo.lock from main's lockfile to eliminate dependency
  version downgrades (anyhow, syn, etc.) that were churn from rebase.
- Add regression test verifying user_id round-trips through save_job
  and get_job in the libSQL backend.

* test: add Postgres-side regression test for user_id persistence in save_job

Mirrors the existing libSQL test (test_save_job_persists_user_id) for the
Postgres backend. Gated behind #[cfg(feature = "postgres")] + #[ignore]
since it requires a running PostgreSQL instance (integration tier).
