The global Backups tab rendered its snapshot list (and the "No backups
yet." empty state) as a bare flex column directly on the tab panel, so
the list section had no visual container -- unlike the Dashboard tab's
cards and the per-app Backups tab's recessed panel. Wrap it in a
.backup-snapshot-panel box (translucent fill + hairline border, matching
.backup-card) so the section reads as a bounded surface.
