feat(chat-character): 캐릭터 상세 조회 응답 스키마 간소화 및 태그 포맷 규칙 적용

- CharacterDetailResponse에서 불필요 필드 제거
  - 제거: age, gender, speechPattern, speechStyle, appearance, memories, relationships, values, hobbies, goals
- 성격(personalities), 배경(backgrounds)을 각각 첫 번째 항목 1개만 반환하도록 변경
  - 단일 객체(Optional)로 응답: CharacterPersonalityResponse?, CharacterBackgroundResponse?
- 태그 포맷 규칙 적용
  - 태그에 # 프리픽스가 없으면 붙이고, 공백으로 연결하여 단일 문자열로 반환
- Controller 로직 정리
  - 불필요 매핑 제거 및 DTO 스키마 변경에 맞춘 변환 로직 반영
