Subject: [PATCH] fix: accept emergency export format in Settings backup
 restore

The Settings "load from file" button only understood its own
sun-catering-backup format. Extend it to also read the
caterium-full-export format produced by the browser-console
emergency export (localStorage + IndexedDB), so an already-downloaded
export file can be restored directly through the UI.
