[BE] 약속 생성 결과 조회 API 구현 (#52)

* test(AttendeeFixture): 참가자용 테스트 fixture 추가

* feat(MeetingService): 약속 생성 결과 조회 로직 추가

* feat(MeetingController): 약속 생성 결과 조회 컨트롤러 추가

* refactor(MeetingController): 불분명한 메서드명 변경

* refactor(MeetingController): API Path 수정 및 불분명한 명명 수정

* test(MeetingController): API Path 수정 및 UUID 오류 발생시 응답 코드 테스트 추가

* refactor(MeetingService): 사용하지 않는 어노테이션 및 Enum 값 제거
