Integrate Log Center for error reporting

- Backend: DRF custom exception handler → Log Center (async, non-blocking)
- Frontend: global error handlers + axios 5xx interceptor → Log Center
- CI/CD: failure step reports build/deploy errors with actual logs
- K8S: add LOG_CENTER env vars to backend deployment
- Registered projects: video_backend, video_web
