fix: KeyboardAwareScrollView collapses to zero height inside auto-sizing parents

[vilson-junior-squadra]

Description
When using KeyboardAwareScrollView inside a wrapper that sizes itself to its content (e.g., a Modal or Bottom Sheet without an explicit height constraint), the scroll view completely collapses to height 0.

This occurs because ReanimatedClippingScrollView within ScrollViewWithBottomPadding applies a hardcoded flex: 1 style. In React Native's Yoga layout engine, a flex: 1 (which acts as flexBasis: 0) child placed inside an unconstrained, self-sizing parent computes its available space as 0.

By substituting flex: 1 with flexGrow: 1 and flexShrink: 1, the layout maintains full backward compatibility for standard full-screen usages (it still stretches to fill an available Flex container) but gracefully falls back to its intrinsic content height when placed inside an auto-sizing wrapper.

Steps to Reproduce
Render KeyboardAwareScrollView inside a View that lacks absolute constraints or explicit flex stretching:

import React from 'react';
import { View, Text, TextInput } from 'react-native';
import { KeyboardAwareScrollView } from 'react-native-keyboard-controller';

// E.g., An auto-height modal overlay container
export const SqueezedModalExample = () => (
  <View style={{ backgroundColor: 'white', borderRadius: 16 }}>
    {/* This will collapse to height 0 and completely disappear from the screen limits */}
    <KeyboardAwareScrollView>
      <Text>Title</Text>
      <TextInput placeholder="Type here..." />
    </KeyboardAwareScrollView>
  </View>
);

Version 1.21.1

Expected behavior
KeyboardAwareScrollView should accurately compute its size based on its children's intrinsic content height when the parent View is dynamically sizing itself.

Actual behavior
The component shrinks to a bounding box of height 0 because of the forced flex: 1 container style, making forms invisible inside auto-sized elements like custom Modals.

Solution
Replaced flex: 1 with { flexGrow: 1, flexShrink: 1 } inside src/components/ScrollViewWithBottomPadding/styles.ts. This effectively gives the container a flexBasis: 'auto', which solves the collapsing sequence.

Thank you @vilson-junior-squadra

Changes look good for me. Let's see what CI tells. If everything is alright then I'll merge this PR (don't pay attention to iOS 26 and iOS 15 simulator tests, they are quite unstable in 1.21.x release and I'm working on making them more stable)
