Clean recursive model detection with proper file counting

- Rewrote load_model function with clean recursive file detection
- Uses os.walk to count files in all subdirectories recursively
- Logs file counts for debugging (Found X video files, Y audio files)
- Requires >10 files in each directory (reasonable threshold)
- Checks both downloaded_models and traditional paths
- Should properly detect the 82 video files and 41 audio files reported by model-status
