   [수정 요약] 이번 변경 사항 (이전 _10 버전 대비)
   ------------------------------------------------------------
   1. 모바일 메뉴 격자: 2열 × 3행 → 3열 × 2행
      - grid-template-columns: repeat(2, 1fr) → repeat(3, 1fr)
   
   2. 메뉴 카드 텍스트 wrap 허용 (3열 좁아진 폭 대응)
      - white-space: nowrap → normal
      - line-height: 1.2 (2줄 wrap 시 답답하지 않게)
      - 긴 라벨("채팅로그&통계", "AI 조건관리")이 잘리지 않고 2줄로 자연스럽게 wrap
      - 격자 row 높이는 가장 긴 카드 기준으로 자동 통일됨
   
   3. 메뉴 카드 패딩 살짝 축소
      - 8px 10px → 7px 8px (3열 공간 확보)
   
   [이전 누적 변경 사항 모두 유지]
   - 통계 카드 모바일 2열 × 3행
   - 사이드바 모바일 그리드 (logo + logout 같은 행, nav 전체 폭)
   - "MEDI82 관리자" 한 줄 배치
   - 활성 메뉴 좌측 강조선 제거 (배경색으로 표시)
   - 라이브 dot 작게 (6px)
   
   [영향 범위]
   - 데스크탑 (768px 초과): 영향 없음
   - HTML 구조: 변경 없음
