chat search now lists local and server-side hits like the file search, and jumping to old messages pages in history with a progress banner and keeps the hit marked

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.

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.
-
-**Rollen & Zuschnitt:** Views verzweigen nie auf Rollen. Module und Settings-Sections deklarieren `AccessRequirement`s (`nextcloud`, `guardian`; `AppModule.requirements`, `Settings._sections`); Views bekommen ein Subjekt + eine Policy, die an genau einer Stelle als pure Funktion aufgelöst wird (Vorbild: `TimetableSubject` + `TimetablePolicy.resolve`, `AbsenceFormPolicy`). `UserRole` nur für Anzeige/Policy-Ableitung.
-
-**Stundenplan:** Ein `TimetableBloc(subject: …)` für alle Fälle (eigener Plan, Fremdplan, Kind). Den globalen Bloc stellt `PrimaryTimetableScope` bereit und tauscht ihn beim Kindwechsel aus; page-scoped Fremdpläne nutzen `ScopedTimetableBloc`. Die Kinderauswahl (`ChildSelectionCubit`) ist modulübergreifend.
-
-**Elternbriefe:** Modul `parentLetters` (nur Eltern-Sessions, `AccessRequirement.guardian`): Lehrer-Mitteilungen aus MarianumConnect mit Gelesen-Status, Kenntnisnahme/Auswahl/Unterschrift pro Kind, Thread und Anhängen. Der Posteingang (`ParentLettersBloc`) ist global (Modul-Badge, Push-Refresh), ein Brief ist page-scoped (`ParentLetterBloc`). Ob und wie geantwortet werden darf, entscheidet der Server (`editable`); `ParentLetterFormPolicy.resolve` macht daraus das Formular. Push: Connect-Direct-Push `type: parent-letter`, Tap-Routing allein über `parentLetterId`. Alle Benachrichtigungs-Taps (lokal gerendert wie FCM) werden von `resolvePushTarget` (`lib/push/push_target.dart`) aufgelöst und in `NotificationTasks.openPushTarget` navigiert – neue Push-Ziele nur dort ergänzen.

+# 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
+`materials/screenshots/{ios/6-5-inch,ipados/13-inch}/` sowie als JPEG-Upload-Kopie
+(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
+{
