feat(project): 홈 화면 업무추가·멤버표시·댓글팝업·실시간 새로고침 추가

- 카드 이름 옆 호버 노출 업무 추가 버튼(기존 업무편집 팝업을 생성 모드로 재사용)
- 카드 이름 아래 배정 멤버 아이콘+이름 표시, 새 프로젝트 모달에서 멤버 다중 선택
- 업무별 댓글 말풍선+개수 표시, 더블클릭 시 카톡형 댓글 전용 팝업
- 확인 안 한 새 댓글은 말풍선이 커지며 반짝임(localStorage 로 확인 여부 추적)
- GET /project/api/live-version 폴링으로 다른 사용자의 변경사항을 자동 새로고침
- 날짜 표기를 yy/mm/dd(요일)에서 mm/dd(요일)로 변경
