[push-deeplink-routing-contract] Generalize push tap routing to DeepLinkDestination

Replace order_status-only NotificationCenter path with a single
DeepLinkDestination enum + PushDeepLinkParser, decoded once in
PushNotificationCoordinator and dispatched via ContentView.route(to:).
Also fixes NotificationService reading userInfo["image"] instead of
the guide's stale "imageUrl" key.
