🔧 Fix HuggingFace Space compatibility

- Update README metadata to use 'docker' SDK (required by HF Spaces)
- Add Dockerfile for containerized deployment
- Set correct app_port for FastAPI service
- Remove unsupported fastapi SDK configuration

This enables deployment to HuggingFace Spaces with Docker runtime.
