chore: [SDK-4788] add local notification compatibility workaround

[fadi-george]

Description

One Line Summary

Add an iOS compatibility workaround demonstrating OneSignal alongside Plugin.LocalNotification without the selector crash reported in issue #132.

Details

Motivation

Plugin.LocalNotification installs a notification-center delegate that does not expose the OneSignal-prefixed selectors used during iOS method swizzling. This example adds a delegate shim to prevent that crash while OneSignal does not yet provide first-party local notification support.

Scope

• Register an iOS delegate shim that exports the OneSignal-prefixed selectors.
• Preserve plugin handling for local notifications and display remote pushes in the foreground.
• Add a simple OneSignal push action and clearer app ID setup to the example.
• Document the workaround, its lifecycle-event limitations, and future replacement by first-party support.
• No SDK public API changes.

Testing

Unit testing

No unit tests were added because this is an example-level iOS delegate integration.

Manual testing

Tested locally via ./run-ios.sh or ./run-android.sh
