feat(TODO): update phases for orders, billing, and calendar features

- Marked orders and billing tasks as complete in the TODO list, detailing the associated components and APIs.
- Introduced a new phase for calendar features, outlining tasks for navigation, data loading, and event management.
- Enhanced the AppDependencies to include BillingApi and MemberOrdersApi for improved billing and order management.
- Updated AppRoot and SettingsScreen to incorporate billing and orders sections, enhancing user navigation and functionality.

-- [ ] **Orders** (`OrdersView.vue`)
-- [ ] **Billing** (`BillingView.vue`)
-- [ ] Rechtliches/UX: ggf. WebView oder Deep-Link, wenn Zahlungsflüsse web-only
+- [x] **Orders** (`OrdersView.vue` / `OrdersPanel.vue` global) – `MemberOrdersApi`, `MemberOrderDtos.kt`, `BillingOrdersScreens.kt` (`GlobalOrdersScreen`)
+- [x] **Billing** (`BillingView.vue`) Kernfluss ohne Web-PDF-Mapping-Editor – `BillingApi`, `BillingDtos.kt`, `BillingClubScreen` (Vorlagen-Upload, Vorschau, Lauf anlegen, PDF erzeugen/teilen, Läufe); Mapping weiter über Browser
+- [x] Rechtliches/UX: Button **Abrechnung im Browser** (`/billing`) für volle Web-Funktion; PDF-Teilen wie Tagebuch-PDF

+## Phase 12 – Kalender (Vereinskalender)
+
+Web-Route: `/calendar` · Referenz: `CalendarView.vue` (Aggregation mehrerer Datenquellen in einer Monatsansicht).
+
+- [ ] **Navigation & Shell:** Tab oder Hub-Eintrag (Berechtigungen klären), Monat vor/zurück, „Heute“, Monatsüberschrift
+- [ ] **Monatsgitter:** 7×6 wie Web, Kennzeichnung „außerhalb Monat“ / heute, Wochentagskopf
+- [ ] **Legende / Filter:** Eventtypen einblendbar (Training, Turnier, Teilnahme offiziell, Punktspiel, Feiertag, Ferien, Trainingsausfall) inkl. Zähler
+- [ ] **Daten laden (parallel, teilfehlertolerant):** gleiche Quellen wie Web – u. a. Tagebuch-Trainingstage, `GET /api/training-times/:clubId`, Trainingsausfälle, Vereins-Turniere, offizielle Teilnahmen, Punktspiele (`MatchesApi`/League-Endpoints), Feiertage/Ferien (Kalenderregion Verein); Fehler pro Quelle wie `sourceWarnings` optional anzeigen
+- [ ] **Logik:** wiederkehrende Trainingszeiten expandieren, Zusammenführen von Slots (`mergeRecurringTrainingSlots`), Ausfälle blenden wiederkehrende Slots aus – Verhalten an Web angleichen
+- [ ] **Trainingsausfall:** Formular (Datum, optional Bis, Grund), Liste im Monat, Speichern/Löschen – API wie Web (`CalendarView` / Backend-Routen zu `training_cancellations` verifizieren)
+- [ ] **Agenda:** sortierte Liste „Termine im Monat“ unter dem Grid
+- [ ] **Event-Aktion:** Klick → sinnvolle Ziel-Navigation (Tagebuch-Tag, Turnier-Detail, Spiel-Detail, externer Link o. ä.) wie `openEvent` im Web
+- [ ] **i18n:** Texte über `MobileStrings` / Keys abstimmen mit Web-`$t` wo sinnvoll
