- Deleted .env and .env.example files to streamline environment variable management.
- Updated docker-compose.yml to utilize env_file for frontend and backend services.
- Enhanced update-docker-env.sh to create separate environment files for development and production.
- Revised README.md to reflect the new environment file structure and setup instructions.
