feat(character-comment): 답글 페이지 UI 및 페이징 스텁 구현

- 댓글 리스트 아이템 터치 시 답글 페이지로 전환 연결
- 상단 뒤로 가기/닫기, 입력 폼, divider, 원본 댓글, 들여 쓰기된 답글 목록 구성
- RecyclerView 최하단 도달 시 더미 데이터 추가 로드(무한 스크롤 스텁)
- 답글 등록/수정/삭제 동작 스텁 처리
- 추가 파일
  - layout: fragment_character_comment_reply.xml, item_character_comment_reply.xml
  - 코드: CharacterCommentReplyFragment, CharacterCommentReplyAdapter
- 변경 파일
  - CharacterCommentListBottomSheet: openReply() 추가
  - CharacterCommentListFragment: 아이템 클릭 시 답글 페이지 진입
