refactor: [equipment] 사진 업로드를 R2(FileStorageSystem) 기반으로 전환

- GCS 스텁 코드를 Cloudflare R2 기반 실제 파일 업로드로 교체
- File 모델 import를 Boards\File에서 Commons\File로 수정
- StoreEquipmentPhotoRequest FormRequest 추가 (파일 검증)
- 다중 파일 업로드 지원 (최대 10장 제한)
- softDeleteFile 패턴 적용 (삭제 시 soft delete)
- ItemsFileController 패턴 준용 (R2 저장, 랜덤 파일명)
