- _legacyRedirect: /updater[/tab] -> /overview[/tab] (security/recovery/history
  fold into the Updates expander -> /overview/updates). /backup is intentionally
  NOT redirected — it stays the operational backup center (locations/migrate/
  snapshots), reached from Overview › Backups.
- Re-point the per-app hotfix chip to /overview/improvements.
- Unhide the existing backup config category in the Admin sidebar so
  engine/schedule/retention config lives under Admin (same generated category
  the backup center binds, so edits stay in sync).
