The per-app Updates tab rendered a bare version/badge bar + detail with no
title, no dividers and no recessed container — unlike the Config / Backups /
Tasks tabs.
- Add a .updater-title block (⬆️ Updates + description, Check/Update actions,
bottom-border divider) mirroring .backup-title.
- Wrap the body in a .updater-detail-container recessed dark panel (same recipe
as .backup-snapshots-container / .tasks-container).
- Separate the Version/Security/Recovery/History sections with divider lines
(scoped to the container; fleet row-details keep their gap-only spacing).
- renderAppDetail() gains an opt-in Version section so the version/badge reads
as a section in the panel; fleet rows omit it (the row head shows it already).
