[Bug]: Map Padding Behavior

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Description of the bug

Currently, when I call setPadding on the map controller, the map view itself correctly adjusts. However, the turn-by-turn navigation UI elements (such as the remaining time, destination panel, or navigation instructions) are not affected by the padding.

This causes those elements to overlap with other parts of the UI, especially when I want to add custom widgets on top of the map.

👉 My question: How can I adjust the padding so that navigation UI elements (time, destination, instructions, etc.) also respect the defined padding?

### Steps to reproduce

Just run the provided code.

### Expected vs Actual Behavior

After calling setPadding, the map camera and navigation UI elements should adjust to avoid overlapping with other UI or custom widgets, but currently, while the map camera respects the padding, the navigation UI elements remain fixed to the screen edge and overlap with overlays and the map's inset region.

### Code Sample

```dart
Future onViewCreated(GoogleNavigationViewController controller) async {
navigationViewController = controller;
await controller.setMyLocationEnabled(true);
if (userLocation.value == null) {
final loc = await controller.getMyLocation();
if (loc != null) userLocation.value = loc;
}
await navigationViewController?.setSpeedLimitIconEnabled(true);
await navigationViewController?.setReportIncidentButtonEnabled(false);
await navigationViewController?.setSpeedometerEnabled(true);
await navigationViewController?.setPadding(EdgeInsets.only(top: 100, bottom: 150));
if (Platform.isAndroid) {
await navigationViewController?.settings.setZoomControlsEnabled(true);
}
}

Future startNavigation() async {
if (!validRoute.value) return;
await navigationViewController?.setNavigationUIEnabled(true);
await GoogleMapsNavigator.startGuidance();
await navigationViewController?.setPadding(EdgeInsets.only(top: 100, bottom: 150));
await navigationViewController?.followMyLocation(CameraPerspective.tilted);
guidanceRunning.value = true;
}
```
