Subject: [PATCH] Refactor Dockerfile for multi-stage build and update start

- Introduced a multi-stage build in the Dockerfile to separate build and runtime environments.
- Added environment variables for production in the runtime stage.
- Updated the start script in package.json to point to the new server entry point.
