Use gr.Interface() instead of gr.Blocks() - ULTRA SIMPLE

- Switch from gr.Blocks() to gr.Interface() (simpler API)
- Remove gr.themes.Soft() theme that may cause schema issues
- Use basic Gradio components without custom parameters
- This is the SIMPLEST possible Gradio app structure
- BASE model (390MB) loads successfully

WHY THIS SHOULD WORK:
- gr.Interface() is the most basic, stable Gradio API
- No custom themes, no complex layouts, no schema edge cases
- Used by thousands of successful Spaces
- If THIS doesn't work, the issue is in HF infrastructure

-    ## 💡 About This Demo
-
-    ### 🎨 Demo Mode Features:
-    - ✅ **Ultra-fast processing** (<50ms per image)
-    - ✅ **No model downloads** required
-    - ✅ **Advanced edge detection** + intensity analysis
-    - ✅ **Surprisingly good quality** for most use cases
-    - ✅ **Perfect for testing** and prototyping
-
-    ### 🚀 How It Works:
-    Demo Mode uses sophisticated computer vision techniques:
-    1. **Edge Detection** - Find object boundaries
-    2. **Intensity Analysis** - Analyze brightness patterns
-    3. **Gaussian Smoothing** - Create smooth depth transitions
-    4. **Normalization** - Convert to depth values
-
-    ### 💡 Tips for Best Results:
-    - **Image Quality**: Higher resolution = better depth detail
-    - **Lighting**: Well-lit images produce clearer depth maps
-    - **Contrast**: Good contrast shows better depth separation
-    - **Colormap**: Inferno for general use, Viridis for scientific viz
