[BUG] Resuming the app does not repaint and leaves the map black

Nobody has claimed this yet.

Steps to reproduce:
1. show a map
2. leave the app (e.g. switch to another app or lock the screen)
3. come back to the app

Problem:
The map stays black and is not redrawn. (Interacting with it triggers a redraw and it is shown again.)

Workaround:
Call `triggerRepaint()` in the `onResume` callback of `AppLivecycleListener`:
```
@override
void initState() {
super.initState();
_lifecycleListener = AppLifecycleListener(
onResume: () => WidgetsBinding.instance.addPostFrameCallback(
(_) => _mapController?.triggerRepaint(),
),
);
}
```

Versions:
- Flutter: `3.44.8`
- mapbox_maps_flutter: `2.27.0`
- Android: `17`

Start by reproducing the black map after backgrounding and resuming the app, then inspect the AppLifecycleListener onResume path and the map controller's triggerRepaint entry point. Done means the map redraws on resume without user interaction, covering the reported Flutter, plugin, and Android versions where appropriate.
