Enhance environment configuration for frontend and CORS support

- Updated update-docker-env.sh to define FRONTEND_URL and streamline CORS settings.
- Modified app.ts to include SERVER_CORS and FRONTEND_URL in allowed origins for both production and development environments.
- Improved output messages in update-docker-env.sh to provide clearer information on URLs and CORS configuration.
