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,
},
});
```

Tái hiện vấn đề trên iOS bằng thiết lập KeyboardAvoidingView, createNativeBottomTabNavigator và thanh tab liquid glass được cung cấp. So sánh hành vi khi có và không có workaround margin tabBarHeight, sau đó theo dõi layout của bottom-tabs và tương tác với cơ chế tránh bàn phím. Được xem là hoàn tất khi nội dung vẫn hiển thị phía trên thanh tab trong suốt mà không cần workaround đó.
