- syncUsagesAfterEdit: use isLocked() instead of !isFinalized() to avoid
syncing quizzes with started candidates (would have destroyed GivenAnswer records)
- syncToQuiz action: use isLocked() instead of hasStartedCandidates() to block
syncing into finalized quizzes that have no started candidates
- QuestionBankService::syncToQuiz: remove internal flush(); callers now
flush once (syncUsagesAfterEdit after the loop, syncToQuiz action after the call)
- QuizRepository::clearQuiz: delete BankQuestionUsage rows and reset
finalized_at inside the transaction (previously orphaned usages blocked
bank question reassignment; finalizedAt reset was a separate non-atomic flush)
- QuizController::finalizeQuiz: add flash when quiz is already finalized
- QuestionBankController::delete: block deletion when any usage references a locked quiz
- BankQuestion::__toString: remove dead null-coalescing on non-nullable string
- SeasonController::addBlankQuiz: align form field with UploadQuizFormType
(add translation_domain: false, use translator for label)
- Use FlashType enum in clearQuiz/finalizeQuiz/unfinalizeQuiz (was raw 'success'/'error' strings)
- Catch UniqueConstraintViolationException in addLabel to handle concurrent duplicate inserts
- Wrap assignToQuiz in a transaction with PESSIMISTIC_WRITE lock to serialise concurrent assignments of the same BankQuestion
- Use Symfony ObjectMapper for BankQuestion/BankAnswer → Question/Answer copy (#[Map(if: false)] on id, season, etc.)
- Track created Question on BankQuestionUsage (nullable FK, onDelete: SET NULL) for unassign/sync support
- Add unassign route: removes the Question copy + usage record
- Add sync route: pushes bank question edits to a finalized-not-started quiz copy
- Auto-sync non-finalized quiz copies on bank question edit; flash warning for finalized-not-started
- Add blank quiz creation (no XLSX required) with new route + template
- Deactivate quiz button now stays on the quiz overview page (redirect_quiz hidden field)
- Remove duplicate h4 titles below the tab bar on all season tabs
- Add migration for bank_question_usage.question_id
- Add Dutch translations for all new strings
