Switch Hugging Face Space to use new Gradio interface

- Update README.md to use 'sdk: gradio' instead of streamlit
- Change app_file to point to app.py with new Gradio interface
- Update app.py to launch the 5-step UI flow instead of streamlit
- Add packages.txt for system dependencies
- This will activate the new step-based interface with floating sidebar
