Closes the loop on the original 2026-05-29 data-loss class: Ralf had
four "Run Backup Now" manifests sitting on disk with
database.backup_file = null because Stage A wasn't yet in place.
The restore wizard would have happily restored any of those four,
bringing back files (photos, PDFs) but leaving the database empty —
silently re-creating the exact data loss the rest of this branch
prevents going forward.
The /restore/list-backups endpoint now returns `database_included`
per row (parsed from the manifest at discovery time). The wizard
uses it to:
- Per-row badge: red "No DB" pill next to any backup where
database_included === false. Tooltip explains the consequence
in plain English: "restoring this will NOT recover the database".
- Selected-card callout: full red banner under the chosen row
when database_included is false, restating the warning + giving
the admin a clear path: "pick a different backup if you have
one with a database dump, or proceed only if files-only is
what you want."
The wizard does NOT block the restore — the admin may genuinely want
a files-only restore (e.g. recovering a deleted photo while keeping
current DB state). The warnings make sure that choice is informed.
