feat(chat-character-comment): 캐릭터 댓글에 글쓴이 ID 추가

- 삭제 API: 본인 댓글에 대해 soft delete 처리
- 신고 API: 신고 내용을 그대로 저장하는 CharacterCommentReport 엔티티/리포지토리 도입
- Controller: 삭제, 신고 엔드포인트 추가 및 인증/본인인증 체크
- Service: 비즈니스 로직 구현 및 예외 처리 강화

왜: 캐릭터 댓글 관리 기능 요구사항(삭제/신고)을 충족하기 위함
무엇: 엔드포인트, 서비스 로직, DTO 및 JPA 엔티티/리포지토리 추가
