Fix Docker deployment issues and add fresh database support

- Fix: Add missing 'click' import to app.py to resolve startup error
- Fix: Update docker-compose.yml volume mappings to use correct persistent storage paths (/opt/digi-s)
- Improve: Enhanced entrypoint.sh for better database initialization
- Update: Configuration files for improved deployment

This resolves the Docker container startup issues and ensures proper persistent storage.
