Subject: [PATCH] fix(exam): reflect authoritative exam state and lock
 engine-graded results

- COC queue status cell shows the server-derived exam state (registered,
  present, sat, passed, failed) instead of the lagging application status.
- Portal examStageFor prefers the server's examState so portal and back
  office never disagree; NOT_SITTING stage added.
- Exam roster shows each candidate's result and lock; Regrade hidden once
  a result exists.
- Record Result modal: only unmarked candidates, empty score boxes (no
  silent zeros), reason required, backend refusals translated.
- Result page: auto-graded marks read-only, per-applicant publish.
- Exam page: session window fields, Add Question menu (bank / Excel /
  scratch), wait metrics panel; PUBLISHED exam status removed.
- Portal: exam window shown, early launch and eligibility refusals explained.
