feat: 일일순회점검 시스템 구축 및 관리 기능 개선

- 일일순회점검 시스템 신규 구현
  - DB 테이블: patrol_checklist_items, daily_patrol_sessions, patrol_check_records, workplace_items, item_types
  - API: /api/patrol/* 엔드포인트
  - 프론트엔드: 지도 기반 작업장 점검 UI

- 설비 관리 기능 개선
  - 구매 관련 필드 추가 (구매일, 가격, 공급업체 등)
  - 설비 코드 자동 생성 (TKP-XXX 형식)

- 작업장 관리 개선
  - 레이아웃 이미지 업로드 기능
  - 마커 위치 저장 기능

- 부서 관리 기능 추가
- 사이드바 네비게이션 카테고리 재구성
- 이미지 401 오류 수정 (정적 파일 경로 처리)
