  * IAuthStorage 接口
  *
  * 对齐 Dart 端 `IAuthStorage`（lib/data/services/storage/iauth_storage.dart）：
- *   - loginToken / loginProvider / guestToken / deviceId / refreshToken / facebookId 字段的 CRUD
+ *   - loginToken / loginProvider / guestToken / deviceId / refreshToken / facebookId / facebookAppId 字段的 CRUD
  *   - `clearAuthData()` 批量清空登录态
  *   - `clearBusinessAuthData()` 仅清空真实用户登录态，保留 guest token / deviceId
  *   - 所有方法返回 `Promise<Result<T>>`，与 Dart `Future<Result<T>>` 对齐
