1.1: Home-Screen-Widget + Siri-Kurzbefehl „Gassi gehen"

App Group group.app.banyaro.ios verbindet App und Widget-Extension
(Entitlements in beiden Targets, CODE_SIGN_ENTITLEMENTS fürs Widget).

Home-Screen-Widget (D):
- BanYaroHomeWidget (klein + mittel): Tagesfoto, Hundename, nächster Termin.
- App schreibt beim Heim-Laden einen Snapshot (HomeWidgetData) in die App
  Group und triggert WidgetCenter-Reload; Snapshot wird bei Logout/401 geleert.

Siri-/Kurzbefehl (E):
- StartWalkIntent „Gassi gehen" + AppShortcutsProvider (öffnet die App).
- WalkLauncher überbrückt Intent → UI: Flag in der App Group, beim Aktivwerden
  eingelöst → Aufnehmen-Tab + Aufnahme-Start (TrackingView.startFresh).
- MainTabView mit Tab-Auswahl (Tags), BanYaroGoApp liest scenePhase.
