refactor(docker, config): streamline directory structure and enhance configuration management

- Removed unnecessary volume mounts for public and logs in docker-compose.yml.
- Updated Dockerfile to create necessary directories under /root/data.
- Modified start.sh to copy files to the new public directory location.
- Enhanced config.go to create default configuration and directory structure if not present.
- Adjusted router.go to serve static files from the new public directory path.
