Discard behaviors with new iOS 26 header buttons

[ferrannp]

I think we would need some native code to do this? Cause even that there is https://github.com/dominicstop/react-native-ios-context-menu, those buttons are defined here unstable_headerRightItems so we don't have access to refs or anything. Probs easier to do natively? We already have usePreventRemove btw, but imo hard to use to achieve this effect with the new buttons. See the video:
