feat: 사용자 작업(감사) 로그 자동 기록 + 관리자 조회 화면

- Auditable 트레잇: 모델 insert/update/delete 시 activity_log 자동 기록
  (조회 제외, before/after JSON, 민감필드 마스킹, 사용자/IP)
- 도메인 모델 28개에 적용 (로그성 테이블 제외)
- 관리자 전용 조회: Admin\ActivityLog (기간/작업/대상/사용자 필터 + 상세 변경내역)
- 라우트 admin/access/activity-logs(+상세), 메뉴 '활동 로그' 추가
- 테넌트 분리: 슈퍼=전체, 지자체관리자=소속 지자체만
