feat: 캘린더 기반 작업 현황 확인 시스템 구현

- 월별 캘린더 UI로 작업 현황을 한눈에 확인 가능
- 미입력(빨강), 부분입력(주황), 확인필요(보라), 이상없음(초록) 상태 표시
- 범례 아이콘(●)을 사용한 직관적인 상태 표시
- 날짜 클릭 시 해당일 작업자별 상세 현황 모달
- 작업자 클릭 시 개별 작업 입력/수정 모달
- 휴가 처리 기능 (연차, 반차, 반반차, 조퇴)
- 월별 집계 데이터 최적화로 API 호출 최소화

백엔드:
- monthly_worker_status, monthly_summary 테이블 추가
- 자동 집계 stored procedure 및 trigger 구현
- 확인필요(12시간 초과) 상태 감지 로직
- 출석 관리 시스템 확장

프론트엔드:
- 캘린더 그리드 UI 구현
- 상태별 색상 및 아이콘 표시
- 모달 기반 상세 정보 표시
- 반응형 디자인 적용
