## ✨ 작업 내용
<!-- 어떤 작업을 했는지 알려주세요! -->
- 전체 더미 데이터 추가(관리자 약 2,400건 / 회원 100만건 / 예약, 일정 약 197만건 / 결제 및 결제 상세 196만건(대략 충전식 간편결제 29.3만건, 카드 147만건, 계좌이체 19.6만건) / 테마 500건 / 매장 263건
- 로컬 애플리케이션 실행 후, 가장 병목이 되는 메인 인기 테마 쿼리만 성능 개선(5회 측정시 API 응답 시간 평균 3300 -> 90ms)

## 🧪 테스트
<!-- 어떤 테스트를 생각했고 진행했는지 알려주세요! -->
변경된 기능은 모두 테스트 반영

## 📚 참고 자료 및 기타
<!-- 참고한 자료, 또는 논의할 사항이 있다면 알려주세요! -->
취소 데이터 등이 들어가있지 않아, 일부 컬럼에서의 Cardinality가 훨씬 낮게 나오는 상황이긴 함. 예약을 예로 들면, 현재는 확정 예약인 데이터만 추가하여 확정 예약이 100%지만, 실제 도메인의 특성상 예약 데이터는 8~90%는 확정 예약일 것으로 생각하여 큰 차이가 없다고 판단하였음.
