Phase 3.6: B+C+D komplett + HealthKit Sync

D.10 401-Handling: APIError.unauthorized, NotificationCenter-Bridge,
  AuthSession.logout() bei 401 → User landet wieder im Login

D.12 PWA-Deep-Links: Settings-Section mit Forum/Hunde/Walks/Settings
  öffnet Safari per https://banyaro.app/#fragment

B.4 Auto-Pause: 2-min-Inaktivität → isAutoPaused, automatischer Resume bei
  nächstem GPS-Update. Settings-Toggle, im UI eigenes Badge "Auto-Pause"
  (grau vs. Pause orange).

C.7 Edit/Delete: RouteUpdateBody + APIClient.patch + APIClient.delete,
  EditRouteSheet (Name/Beschreibung/Public), Menu in Toolbar (nur eigene
  Touren), Alert für Delete.

C.9 Statistik-Tab: neuer Tab "Statistik" zwischen Hunde und Mehr. Filtert
  /api/routes auf meine Touren, rechnet Woche/Monat/Allzeit (Distanz, Dauer,
  Touren), Längste Tour, aktuelle Streak (Tage in Folge).

B.5 Walk-Review: Map-Header an die Spitze des FinishWalkSheet-Forms.

B.6 Geo-Fotos: CapturedPhoto (Data + GPSPoint?), PhotoLocation @Model in
  SwiftData. Kamera während Walk taggt mit tracker.points.last. Nach Upload:
  foto_url aus Response → PhotoLocation persistiert. MiniRouteMap rendert
  Annotations mit Tap-Callback, PhotoViewerSheet zeigt Foto fullscreen.

C.8 Share PNG+GPX: RouteShareImage (MKMapSnapshotter + Polyline overlay +
  SwiftUI ShareCard via ImageRenderer), GPXExporter (Tempfile mit XML),
  ShareSheet (UIActivityViewController-Wrapper), Menu in Route-Toolbar.

D.11 Icon-Varianten: AppIcon-Dark (0.45 Brightness), AppIcon-Tinted
  (Grayscale + Kontrastverstärkung), Contents.json mit appearance entries.

A.2 HealthKit: BanYaroGo.entitlements (com.apple.developer.healthkit),
  NSHealthShare/UpdateUsageDescription. WalkHealthSync.shared mit
  HKWorkoutBuilder (.walking) + HKWorkoutRouteBuilder, Timestamps gleichmäßig
  über Walk-Dauer verteilt. Settings-Toggle mit Permission-Request.
