// services/api/test/photos-admin.e2e-spec.ts —— P1b Task 4 管理照片列表 e2e
// （先写后实现）。真实 app + MySQL。覆盖：
//   ① owner GET /albums/{albumId}/photos：全部可见性状态可见（unpublished/
//      published/hidden/deleted，含 uploaded/processing/processing_failed 处理
//      态），(uploadedAt,id) DESC 稳定倒序（同 uploadedAt 以 id DESC 决胜），
//      条目 = PhotoRecord + uploader{userId,account,displayName} 脱敏内嵌
//      （无邮箱/密码/状态字段；契约 PhotoRecord 不含 errorCode——管理侧对失败
//      的可见性经 processingState=processing_failed 表达）；未完成上传
//      （pending_upload、uploadedAt NULL）不入列表（排序键未就绪，见服务注释）；
//      他册照片不入列表；
//   ② visibility 过滤（四态逐一 + 非法值 400）；categoryId 过滤（含与
//      visibility 组合；幽灵/跨册分类 400）；
//   ③ 游标分页：limit=3 三页跨页无重复、尾页 hasMore=false；非法 cursor /
//      limit 越界 → 400；
//   ④ 权限：协作者（非 owner 成员）403 AUTH_FORBIDDEN；外人员工 404
//      ALBUM_NOT_FOUND；公司 admin 200；幽灵相册 404；未认证 401。
