feat: add approval queue UX with position labels, queue preview, and count badges

- ChatPane: show 'Approval 1 of N' label, queued-approvals accordion preview,
  queue count badge in header, and hint text for queue advancement
- Sidebar: show '+N queued' count next to 'Awaiting approval' badge
- ActivityPanel: show total approval count in header badge
