Refactor Dockerfile for improved build process and configuration management

- Updated the Dockerfile to use the latest base image and streamline the multi-stage build process.
- Enhanced dependency installation by copying additional configuration files and using the `--frozen-lockfile` option.
- Set environment variables for production settings and localization.
- Adjusted the command to start the application, ensuring it runs the correct entry point.
