added automated App Store screenshots via iOS simulators and fastlane deliver

tool/screenshots_ios.sh runs the existing demo-login integration test on
iPhone 6.5" (iPhone 14 Plus) and iPad 13" simulators, stores the canonical PNGs
under materials/screenshots and mirrors alpha-free JPEGs to
ios/fastlane/screenshots for `fastlane upload_screenshots`.

Fixed the demo router answering timetable/custom-events with a week, which
crashed the inline iOS widget refresh after a demo login. The screenshot test
now skips the one-time Talk notification dialog and waits longer for the app
shell on cold simulators.

 **Settings:** Pro Feature ein Freezed-Modell unter `lib/storage/`, persistiert via HydratedBloc.
 
+**Session:** Die aktive Sitzung liegt in `SessionManager().current` (`lib/session/`). Nextcloud-Zugriffe nur über `SessionManager().requireNextcloud()`. Abmelden ausschließlich über `SessionLifecycle.signOut()`. Die Keychain-Keys in `SessionKeys` sind eingefroren (Bestandsinstallationen, iOS-NSE).
+
+**Mehrere Konten:** Die `SessionKeys`-Slots, der MC-Token und die Group-Keychain spiegeln immer das *aktive* Konto; inaktive Konten liegen im Tresor (`accounts_index` + `account_vault_<id>`, `lib/session/account_codec.dart`). Wechseln/Hinzufügen/Entfernen nur über `SessionLifecycle` (`switchTo`, `beginAddAccount`/`finishLogin`/`cancelAddAccount`, `removeInactive`), danach `AccountBloc.activated(id)`. Lokale Daten sind pro Konto getrennt (`AccountStorage`: eigene HydratedBloc-Box; der Request-Cache `CacheStore` folgt dem aktiven Konto mit eigenem Verzeichnis); nur die Settings liegen in der globalen Box. `SessionManager().sessionEpoch` steigt bei jedem Kontowechsel – asynchrone Arbeit prüft damit, ob ihr Ergebnis noch zum aktiven Konto gehört. Was ein Konto außerhalb seines Speichers hinterlässt (Tray, Push-Schlüssel, Downloads), räumt `SessionWipe` auf. Alle Pro-Konto-Blocs gehören in `AccountScope` – er wird per Konto-ID neu aufgebaut (samt `MaterialApp`/Navigator). Push ist nur für das aktive Konto registriert.

+# Fastlane – App-Store-Screenshots & Upload
+
+iOS-Gegenstück zu `android/fastlane`. Die App muss dafür **nicht** neu gebaut
+werden – der Demo-Modus (`demo@`-Login) liefert die kompletten Inhalte aus
+Fixtures.
+
+## 1. Screenshots aufnehmen

+Aus dem **Client**-Wurzelverzeichnis:
+
+```bash
+tool/screenshots_ios.sh
+```
+
+Fährt „iPhone 14 Plus“ (6,5″, 1284×2778) und „iPad Pro 13-inch (M5)“
+(13″, 2064×2752) nacheinander durch und legt die PNGs in

+(App Store Connect lehnt Alpha-Kanäle ab) in `screenshots/de-DE/` ab. Fehlende
+Simulatoren legt das Skript selbst an.
+
+- Nur eine Größe: `PROFILES="iphone" tool/screenshots_ios.sh`
+- Andere Simulatoren: `IPHONE_SIM="iPhone 11 Pro Max" IPAD_SIM="…" tool/screenshots_ios.sh`
+
+App und Schlüsselbund der verwendeten Simulatoren werden dabei zurückgesetzt.
+
+## 2. Hochladen
+
+fastlane installieren (`brew install fastlane`), in App Store Connect unter
+*Benutzer und Zugriff → Integrationen → App Store Connect API* einen Key mit
+Rolle *App-Manager* anlegen und als JSON ablegen:
+
+```json

+
+```bash
