feat: enable persistent local archives and smart profile fallback

Browse Source 
Key changes:
- Enabled full metadata caching for local folder archives, allowing them to load instantly from IndexedDB without re-uploading.
- Implemented oldest-image fallback for profiles missing an explicit profile picture.
- Restored folder-name-to-username detection for local archive uploads.
- Optimized scan indexing to track all image files for fallback use.
