refactor: 커뮤니티 관련 통합 테스트 데이터 fixture 메서드로 변경 (#335)

* feat: BoardFixture에 Board 생성 메서드 추가
- 지연로딩 문제를 방지하기 위해 Board 조회 시 fetch join 사용

* feat: PostFixture에 Post 생성 메서드 추가

* feat: PostImageFixture에 PostImage 생성 메서드 추가

* feat: CommentFixture에 Comment 생성 메서드 추가

* refactor: Community 관련 데이터 fixture 메서드로 변경

* refactor: BaseIntegrationTest 제거

* refactor: BoardFixture에서 BoardCode enum 상수 일관되게 사용
