feat: Global E2E tests, multi-agent fixes, SIP agent tracing

- 13 Global Hospital smoke tests (CC Agent + Supervisor)
- Auto-unlock agent session in test setup via maint API
- agent-status-toggle sends agentId from localStorage (was missing)
- maint-otp-modal injects agentId from localStorage into all calls
- SIP manager logs agent identity on connect/disconnect/state changes
- seed-data.ts: added CC agent + marketing users, idempotent member
  creation, cleanup phase before seeding
- .gitignore: exclude test-results/ and playwright-report/
