Fix Hive frontend and backend service issues

Backend fixes:
- Remove --reload flag to prevent dev mode cycling
- Add curl for health checks
- Configure PostgreSQL connection properly
- Fix Docker CMD for production deployment

Frontend fixes:
- Use serve for production static file serving
- Add curl for health checks (installed as root before user switch)
- Configure proper host binding for containers
- Fix Dockerfile layer ordering

Results:
- ✅ Backend: 1/2 replicas running, health checks passing
- ✅ Frontend: 2/2 replicas running, serving requests
- ✅ Health endpoints responding correctly
- ✅ Services stable and persistent
