feat(usage): PowerUse-Zeitfenster + Handoff-Schwellwert als Settings

Drei neue app_settings-Spalten (Migration AddPowerUseWindow): power_use_window_start/end (HH:mm, lokal, nullable) und power_use_handoff_pct (NOT NULL DEFAULT 95, geclampt 50-99). Die Fensterlogik liegt als reine Funktion in PowerUseWindow (Contains/Normalize/IsOpen): beide Grenzen leer oder nur eine gesetzt = rund um die Uhr, Ende vor Start wrappt ueber Mitternacht, Grenzen halboffen. Geprueft wird in ComposeHandlerPromptAsync, also pro Phase zum Zeitpunkt des Prompt-Baus - die Uhr ist per Func<DateTime> injizierbar. Bedienung im Usage-Monitor neben dem PowerUse-Toggle (Commit auf Blur/Enter, ein Write fuer alle vier Felder); in Settings->General unsichtbar, aber load->save durchgereicht. Nebenbefund, gleicher Pfad: AppSettingsRepository.UpdateAsync kopiert Feld fuer Feld und hat ModelPresets, PowerUseEnabled und ListHandlerMaxHandoffs nie geschrieben - jeder Save dieser drei war still wirkungslos. Mit ergaenzt und per Round-trip-Test gepinnt.
