feat(claude-do): UI: Gate-Schwellen im Settings-Modal (General)

Macht die zwei Schwellen einstellbar. Setzt den Data-Subtask (Felder in `app_settings`) und den Hub-Subtask voraus.

**Zu bauen**
1. `AppSettingsDto` durchziehen: `WorkerHub` (`GetAppSettings` / `UpdateAppSettings`) und der UI-seitige Record in `WorkerClient.cs` bekommen `UsageGateFiveHourPct` und `UsageGateSevenDayPct`.
2. `GeneralSettingsTabViewModel`: zwei `[ObservableProperty]`-Felder, Validie
