Backend:
- Fail fast on empty JWT_SECRET at startup
- Restrict CORS to explicit methods (GET/POST/PUT/DELETE/OPTIONS) and
headers (Authorization, Content-Type) instead of Any
- Add 1MB request body size limit (DefaultBodyLimit)
- Add gRPC status mappings: DeadlineExceeded->408, Cancelled->499,
AlreadyExists->409, ResourceExhausted->429, Unavailable->503
Frontend:
- Guard ErrorBoundary console.error behind import.meta.env.DEV
- Read VITE_API_URL and VITE_WS_URL from env vars with fallbacks
- Add max reconnect attempts (50) to WebSocket manager
- Tune React Query: staleTime 10s, refetchInterval 15s,
disable refetchOnWindowFocus to prevent thundering herd
