Deploy real API calling version

- Implements Gradio Client API to call official HunyuanVideo-Foley Space
- Falls back to Hugging Face Inference API as secondary option
- Smart API inference with multiple fallback strategies
- No local model loading - solves 16GB memory limit issue
- Real AI audio generation through remote API calls
- Comprehensive error handling and user feedback
- Minimal dependencies focused on API calling
