feat(notices): 권한 관리 화면과 동일한 3-패널 UI 로 전면 재설계

요청 사항 반영:
1) UI 패턴을 권한 관리 화면(admin-panel AuthManagement)과 통일
   - 좌측 (260px): 수신자 그룹 목록 + 검색 + [+ 생성] 버튼
   - 우측 상단: 그룹 멤버 / [‹ 추가 / 제거 ›] / 멤버 아닌 사용자 풀
     (권한있는/권한없는 직원 양쪽 패널 패턴 그대로)
   - 우측 하단: 발송 내용 (제목/본문/이미지/링크) + 발송 버튼
2) 그룹 추가/제거를 클릭 한 번으로 (전체 풀에서 체크 후 추가 → 멤버 패널로 이동)
3) 더블클릭으로 그룹 이름/설명 수정 또는 삭제
4) [전체 구독자에게 발송] 옵션 — 그룹 선택 없이도 전체 푸시 가능
5) 화면 안의 '최근 공지' 카드 제거 — 좌측 메뉴 [푸시알림 발송이력] 로 일원화
