choyoungwoo9 · choyoungwoo9 · commit d0706f202155 · 2024-10-02T19:06:56.000+09:00
- 엔티티
  - 프로젝트 참여요청 엔티티 추가
  - 프로젝트 엔티티에 프로젝트 참여요청 프로퍼티 추가
- 레포지토리에서 DB에 프로젝트 참여요청 생성 메서드 추가
- 서비스에서 프로젝트 참여요청 생성 메서드 추가
- 컨트롤러에서 프로젝트 참여요청 제출 메서드 추가
- 프로젝트 참여요청 E2E 테스트 추가
  - 성공 상황
  - 인증실패 상황
  - 유효하지 않은 프로젝트 링크 상황
  - 이미 회원인 유저가 요청한 상황
  - 이미 참여요청한 유저가 다시 참여요청한 상황
