fix: dead Add Note buttons and no-op row click in admin review pages

- verification/[id].tsx: "Add Note" in the Reviewer Notes panel had no
  onClick — wired to the existing POST /api/admin/verifications/:id/notes
  endpoint.
- approval/index.tsx: Decision Notes textarea was uncontrolled and its
  "Add Note" button was a no-op; there's no standalone notes endpoint
  for approval_requests, so the textarea is now bound to state and its
  value is sent as the rejection reason when the reviewer rejects
  (the only channel the backend currently supports).
- support.tsx: removed a no-op onClick={() => {}} on the case row —
  the row isn't actually clickable, only the adjacent "View" link is
  (though that link's target route doesn't exist yet — flagged
  separately, out of scope here).
