feat: dockerize app and convert to pyproject setup

- Add pyproject.toml with proper metadata and dependency groups
- Create multi-stage Dockerfile for backend
- Add docker-compose.yml with dev/prod profiles
- Create frontend Dockerfile with nginx
- Add .dockerignore for optimized builds
- Update README with Docker instructions and troubleshooting
- Remove requirements.txt in favor of pyproject.toml
- Ensure data persistence with Docker volumes
