FINAL FIX: Python 3.10 + optimized dependencies + clean Gradio app

Add runtime.txt for Python 3.10 and use TensorFlow 2.15.0

Simplify dependencies - use tensorflow-cpu and remove explicit numpy/pillow

Update TensorFlow to 2.20+ for Python 3.13 compatibility

Fix build: remove gradio from requirements
