Tab bar does not respect KeyboardAvoidingView on iOS (Liquid glass) - Renders on top of it

### Before submitting a new issue

- [x] I tested using the latest version of the library, as the bug might be already fixed.
- [x] I tested using a [supported version](https://github.com/reactwg/react-native-releases/blob/main/docs/support.md) of react native.
- [x] I checked for possible duplicate issues, with possible answers.

### Bug summary

When using KeyboardAvoidingView with react-native-bottom-tabs on iOS with the new "liquid glass" tab bar style, the keyboard-avoiding content is rendered underneath the tab bar. The KeyboardAvoidingView's padding/height calculation doesn't account for the translucent tab bar height, causing the bottom portion of the content to be obscured.

Current workaround:

const tabBarHeight = useBottomTabBarHeight();

```

{/* content */}

```

### Steps to reproduce

1. Set up a screen with bottom tabs using react-native-bottom-tabs
2. Wrap content in a KeyboardAvoidingView with behavior="padding"
3. Use a view inside it with 100% height or flex 1.
4. The tab bar renders on top of it.

### Reproducible sample code

```js
import React from 'react';
import {
KeyboardAvoidingView,
Platform,
TextInput,
View,
StyleSheet,
Text,
} from 'react-native';
import { createNativeBottomTabNavigator } from 'react-native-bottom-tabs';
import { NavigationContainer } from '@react-navigation/native';
import { useBottomTabBarHeight } from 'react-native-bottom-tabs';

const Tab = createNativeBottomTabNavigator();

function HomeScreen() {
const tabBarHeight = useBottomTabBarHeight();

return (


KeyboardAvoidingView + Bottom Tabs Bug




);
}

function SettingsScreen() {
return (

Settings

);
}

export default function App() {
return (


require('./assets/home-icon.png'),
}}
/>
require('./assets/settings-icon.png'),
}}
/>


);
}

const styles = StyleSheet.create({
container: {
backgroundColor: '#fff',
},
content: {
flex: 1,
padding: 20,
justifyContent: 'flex-end',
},
title: {
fontSize: 20,
fontWeight: 'bold',
marginBottom: 10,
},
spacer: {
flex: 1,
},
input: {
borderWidth: 1,
borderColor: '#ccc',
borderRadius: 8,
padding: 15,
fontSize: 16,
},
});
```

Reproduziere das Problem auf iOS mit dem bereitgestellten KeyboardAvoidingView-, createNativeBottomTabNavigator- und liquid glass-Tab-Bar-Setup. Vergleiche das Verhalten mit und ohne die tabBarHeight-Margin-Workaround und verfolge anschließend das Layout von bottom-tabs sowie die Interaktion mit der Keyboard-Vermeidung. Als erledigt gilt die Aufgabe, wenn der Inhalt oberhalb der transparenten Tab-Bar sichtbar bleibt, ohne diesen Workaround zu benötigen.
