- Added getUnregFilePath() helper to construct full path for unregistered files
- Updated template to use getUnregFilePath() for thumbnail loading
- Updated loadFiles() to load thumbnails for unregistered files with constructed paths
- Unregistered files now show thumbnails instead of placeholder icons
