fix: address CodeRabbit review findings on PR #183

- Add SeasonVoter::EDIT guard to QuizQuestionController::view()
- Add full-count check in reorder() to reject partial ordering payloads
- Retry once in _persistOrder(); lock drag and show dismissible alert on failure
- Remove tabindex="-1" from correct-answer toggle button (accessibility)
- Replace 'EMPTY'|trans placeholder with proper copy
- Add data-modal-title to question bank Edit button to prevent stale title
