fix(ios): forward APNs device token from AppDelegate to Capacitor

ROOT CAUSE of iOS push not working: Capacitor 7's default AppDelegate.swift
template does NOT implement application(_:didRegisterForRemoteNotificationsWithDeviceToken:)
or ...didFailToRegisterForRemoteNotificationsWithError:. So when @capacitor/push-
notifications calls registerForRemoteNotifications(), iOS fetches the APNs token
and calls the AppDelegate, but nothing posts .capacitorDidRegisterForRemoteNotifications,
so the plugin never delivers the token to JS. register() 'succeeds' yet neither the
registration nor registrationError event fires — proven by server push telemetry
(register-called logged; no token, no error; device_tokens stayed empty).

inject-push.js adds the two forwarding methods to the CI-generated AppDelegate
(idempotent, tolerant — never fails the build), wired into ios-patch.sh after the
audio patch. Verified against the real Capacitor 7 template: methods land inside
the class, braces balance, both listeners present.

This is the missing piece alongside the earlier aps-environment entitlement fix and
the server APNs config. Needs a fresh Codemagic build to take effect.
