Enhance Docker and Build Configuration

- Added support for build arguments in Dockerfile to specify UID, GID, version, build time, and commit hash.
- Updated docker-compose.yaml to utilize UID and GID for non-root user execution, improving file permission handling.
- Introduced entrypoint.sh script to manage user permissions and environment setup at container startup.
- Enhanced application logging to include version information during startup.
- Updated README with new instructions for running the application with specific user IDs and environment variables.
