[L5-참고의견]
RoomUpdatedEvent를 통해 SSE 이벤트를 발급할 때 Question의 사용은 quiz.getQuestions().size()으로 문제의 크기만 사용하는 것으로 보입니다.
하지만, getQuizWithQuestionsById는 해당 퀴즈의 모든 문제들을 Fetch Join 해오기 때문에 불필요한 오버헤드의 발생이 존재하는 것 같습니다.
추후 가능하다면 RoomUpdatedEvent 리팩토링을 통해 qustion size를 따로 받아오는 방향으로 개선해 보는 것도 좋다는 생각이 들었습니다.

필요한 데이터만 가져오도록 쿼리를 findByQuizId와 getQuestionsCount쿼리로 분리해 변경하였습니다!

- 퀴즈가 문제의 정보까지 fetch join하는 쿼리에서 findQuizById 쿼리로 문제는 Lazy 로딩하도록 변경
