Expand asset upload script to include audio files and rename tasks

- Rename upload task from upload-images to upload-assets for clarity  
- Update script to handle additional audio file types (m4a, mp3, wav, ogg, aac, flac) alongside images  
- Modify scanning, hashing, uploading, and manifest generation to support both images and audio  
- Improve manifest and variable names to reflect broader asset coverage  
- Ensure idempotence by skipping already uploaded assets  
- Update logs to reflect total assets processed, enhancing monitoring and debugging
