[Feature Request] [iOS] Migrate to UIKit's scene-based lifecycle

[REQUIRED] Step 1: Describe your environment

flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 3.38.7, on macOS 15.6 24G84 darwin-arm64, locale en-US)
[✓] Android toolchain - develop for Android devices (Android SDK version 36.0.0)
[✓] Xcode - develop for iOS and macOS (Xcode 16.0)
[✓] Chrome - develop for the web

Plugin Version

google_mobile_ads: ^7.0.0

[REQUIRED] Step 2: Describe the problem

According to the Flutter official breaking changes document:
https://docs.flutter.dev/release/breaking-changes/uiscenedelegate

During WWDC25, Apple announced the following:
In the release following iOS 26, any UIKit app built with the latest SDK will be required to use the UIScene life cycle, otherwise it will not launch.

I noticed that the google_mobile_ads plugin (v7.0.0) is still using the old AppDelegate approach for lifecycle events:
https://github.com/googleads/googleads-mobile-flutter/blob/v7.0.0/packages/google_mobile_ads/ios/Classes/FLTGoogleMobileAdsPlugin.m#L101

Is there any plan or ongoing work to migrate the google_mobile_ads plugin to support UISceneDelegate?

Hi @henryyiu-iet

Thank you for bringing this to our attention.

This as a valid feature request and we will work on updating the plugin to correctly handle UIScene and connectedScenes lookups to ensure future compatibility.

We will keep this issue open to track the migration. thanks!
