Subject: [PATCH]  FIX: Restore Mouth Mask Functionality

 MOUTH MASK FIXED:
- Added mouth mask processing back to swap_face_ultra_fast()
- Mouth Mask toggle now works properly
- Only processes mouth mask when enabled (no FPS impact when off)
- Kept FPS optimization while restoring functionality

 FUNCTIONALITY RESTORED:
- create_face_mask() for target face
- create_lower_mouth_mask() for mouth area
- apply_mouth_area() for mouth blending
- draw_mouth_mask_visualization() for debug display

 FPS STATUS:
- Maintained 10-19 FPS improvement
- Mouth mask only processes when toggle is ON
- No FPS impact when mouth mask is OFF
- Best of both worlds: speed + functionality

 WHAT WORKS NOW:
- Mouth Mask toggle
- Show Mouth Mask Box toggle
- Fast face swapping
- Good FPS performance
