[iOS] `react-native-screens` v4.19.0 breaks the global back swipe gesture on pager views

## Environment

- iOS 26
- `react-native-screens` v4.19.0
- Any `react-native-pager-view` version (tested 6.8.0, 6.8.1, 8.0.0)

## Description

I have filed the same issue with `react-native-screens` here: https://github.com/software-mansion/react-native-screens/issues/3512
Since this is an issue with the interaction between these two libraries, I thought it was worth opening one here too.

After upgrading to `react-native-screens` v4.19.0, the global back gesture does not work if it's on top of a pager view. I would speculate it's due to https://github.com/software-mansion/react-native-screens/pull/3420

**Expected behaviour:** I am able to swipe back to the previous screen.

This is exactly the same problem as I have with https://github.com/callstack/react-native-pager-view/issues/1006, except now it's happening on all versions

## Reproducible Demo

https://github.com/mozzius/pagerswipe-repro

Inizia eseguendo la demo riproducibile all’indirizzo https://github.com/mozzius/pagerswipe-repro con react-native-screens v4.19.0 e una versione elencata di react-native-pager-view, quindi leggi la issue 3512 collegata di react-native-screens. Il lavoro è completato quando lo swipe globale per tornare indietro torna alla schermata precedente mentre è attiva una vista pager.
