[Feat] - 관리자 공개 코스 삭제 권한 추가 (v2) (#174)

* revert: 관리자 삭제 권한 관련 변경사항 전체 롤백

- PublicCourseService: isAdmin 체크, 스크랩 삭제, Record FK null 처리 제거
- RecordRepository: nullifyPublicCourseIn 메서드 제거
- f8b4c26 상태로 원복

* feat: 관리자 공개 코스 삭제 권한 추가

- userId 280(관리자) 소유권 검증 우회
- EntityManager JPQL로 Record FK null 처리
- Scrap 삭제 후 PublicCourse 삭제 (FK 순서 보장)
