- `DeleteFavoriteUseCase`：POST delete → 同步删本地 DB
- `FavoritesViewModel`：分页/刷新/加载更多/删除，DB Stream 驱动
- `FavoritesPage`：列表 + RefreshIndicator + Dismissible 左滑删除 + 类型图标 + 空状态
- `AppRouteName.settingsFavorites` + 路由注册 + auth guard
- `settings_page.dart` 收藏行 onTap 接入导航

## 最近呼叫（框架，API 对接待续）
- `CallLogRequest` / `FetchCallLogsUseCase` / `RecentCallsViewModel`
- `RecentCallsPage`：双 Tab（全部/未接）+ _CallLogTile（图标/时长/时间）
- `AppRouteName.settingsRecentCalls` + 路由注册
