`TextInput`: setting `activeUnderlineColor` to `"transparent"` makes the `TextInput` unable to receive touch events

### Current behaviour
Touch events are not registered.

I believe this is related to the New Architecture, per [this issue filed on React Native](https://github.com/facebook/react-native/issues/50465). However, the resolution to this issue was that this is expected behavior, so this is still a bug here.

### Expected behaviour
Touch events should register.

### How to reproduce?
Create a `TextInput` and set the `activeUnderlineColor` to `"transparent"`. (Even a very light gray seems to trigger the issue.)

### What have you tried so far?

### Your Environment

| software | version
| --------------------- | -------
| ios | 18
| android | 16
| react-native | 0.79.3
| react-native-paper | 5.14.5
| node | x.x.x
| npm or yarn | x.x.x
| expo sdk | x.x.x

Start by reproducing the issue with a React Native Paper TextInput using activeUnderlineColor="transparent" on the listed iOS and Android versions. Trace the TextInput entry point and compare touch handling with and without the color setting; done means touch events register normally while the underline remains transparent.
