Merge claude/1

The fleet Overview area (Overview · Updates · Improvements · Backups) and the
backup center now live under App Center, so the standalone top-nav items are
redundant. Top nav is now Dashboard · App Center · Admin · Tasks.

- Remove the Backups and Updates anchors from topbar.html.
- Remove the nav{} blocks from updater/backup feature.json + manifest (so they
  don't resurface when the nav kernel lands).
- Highlight App Center for /overview and /backup; drop the dead /updater branch.
