fix: address CodeRabbit review findings

- 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
