sihooandClaude Sonnet 5 a3894cc878 스마트기기 반출 대장: 전체 학생 허용 + 많은 시간요청 학생 검토 기능 추가
- "전체 학생 허용" 아이콘을 새로고침 버튼 옆에 추가 - 대기 중인 요청을
  한 명씩 승인하는 대신 확인 팝업 후 한 번에 전부 승인
- "많은 시간요청 학생" 아이콘 추가 - 학생이 시간을 비정상적으로 길게
  적어낼 수 있으니, 2시간 이상 신청한 대기 중인 요청만 따로 모아 보여줌
  (해당 건수를 빨간 배지로 표시). 목록에서 바로 승인/거절 가능
- 컨트롤러에 durationHours/longPendingRequests/approveAllPending 추가.
  일괄 승인은 서버에 batch API가 없어서 대기 요청마다 순서대로
  승인 요청을 보내고 마지막에 한 번만 새로고침
