feat(diagnostics): fix Event Stream and Provider Health Status in admin UI

Backend fixes:
- Add __init__.py to api/app/services/ and api/app/routers/ directories (required for proper module imports)
- Add __init__.py to api/app/monitoring/ directory
- Fix circular import in routers by moving require_admin to auth.py
- Fix import paths in admin_diagnostics.py (app.services.events not api.app.services.events)
- Fix import paths in admin_providers.py (app.auth not api.app.auth)
- Add admin authentication to all events and provider health endpoints
- Initialize ProviderHealthMonitor in app.state on startup
- Add traceback logging for router mount failures

Router endpoints now working:
- /admin/diagnostics/events/types ✅
- /admin/diagnostics/events/recent ✅
- /admin/diagnostics/events/sse ✅
- /admin/providers/health ✅

This resolves the 404 errors in the Event Stream and Provider Health Status sections of the Diagnostics page.
