Refactor Docker setup and remove unused files

- Updated docker-compose.yml to rename backend and frontend container names for clarity.
- Added volume mappings for frontend and backend services to persist data.
- Removed obsolete files related to frequency response extraction, including Python scripts and output data files.
- Adjusted backend port configuration in main.py to align with new service architecture.
- Enhanced logging for file upload paths in models.py for better traceability.
