feat: Auditable 트레이트 구현 및 97개 모델 적용

- Auditable 트레이트 신규 생성 (bootAuditable 패턴)
  - creating: created_by/updated_by 자동 채우기
  - updating: updated_by 자동 채우기
  - deleting: deleted_by 채우기 + saveQuietly()
  - created/updated/deleted: audit_logs 자동 기록
- 기존 AuditLogger 패턴과 동일한 try/catch 조용한 실패
- 변경된 필드만 before/after 기록 (updated 이벤트)
- auditExclude 프로퍼티로 모델별 제외 필드 설정 가능
- 제외 대상: Attendance, StockTransaction, TodayIssue 등 고빈도/시스템 모델
