Convert to Dockerized Gradio app for proper Hugging Face deployment

- Add Dockerfile with Python 3.10-slim base image
- Configure Docker-compatible Gradio launch settings
- Update README.md to use sdk: docker instead of sdk: gradio
- Add .dockerignore to exclude unnecessary files
- Set proper server configuration for Docker container
- Add health check and expose port 7860
- Ensure compatibility with Hugging Face Spaces Docker template
