- Add health check endpoint for Cloud Run monitoring
- Update server to listen on 0.0.0.0:8080 for Cloud Run compatibility

- Improve error handling and logging throughout request lifecycle
Update Dockerfile to install google-auth-library dependency and expose
port 8080 instead of port 80.
Replace Python http.server with Express to handle:
- Large IAP JWT headers that caused 500 errors
- API request proxying with GCP identity tokens
- Static React build serving with SPA fallback
Update api.ts to use relative URLs in production for proxy routing.
