feat(character-comment): 캐릭터 댓글 리스트 등록/목록/신고 API 연동 및 DI 등록

fix(character-comment): 캐릭터 댓글 리스트 무한 스크롤에서 cursor null 시 추가 호출 방지

- CharacterCommentApi/Repository 추가
- AppDI에 API/Repository 등록
- CharacterCommentListFragment: 등록 버튼 클릭 시 API 호출로 전환, 커서 페이징 목록 로드 적용, 신고 API 연동
- 로딩/에러 처리 및 중복 로드 방지 플래그 추가

- 스크롤 리스너에 canLoadMore 조건 추가(초기 또는 cursor 존재 시에만 호출)
- loadMore()에 종료 가드 추가(adapter 비어있지 않고 cursor null이면 반환)
- 댓글 1개인 경우 동일 내용 반복 로딩 문제 해결
