feat: configure Coolify deployment for production

- Fix docker-compose.yml for production: use postgres:15-alpine, remove
  container names, remove postgres external port, set FRONTEND_URL to
  server IP, use empty VITE_API_URL for nginx proxy
- Add production server CORS origins to backend
- Add deploy job to GitHub Actions CI/CD pipeline
