[iOS] Fix user interaction never being reenabled when cancelling a video fullscreen dismiss gesture

[mozzius]

Description

Fixes #3388

In #3173, interaction is disabled during screen transitions. However, when using the native fullscreen video player from expo-video, there is an edge case - you can cancel your swipe gesture, which causes user interaction to be disabled and never reenabled. The order of events is this:

• willMoveToWindow fires, disabling user interaction
• I cancel the swipe gesture by swiping up instead of down
• willMoveToWindow again, as we're moving back to the video player
• viewDidAppear does not fire, because nothing actually changed

Therefore user interaction is never reenabled, even though the transition is over

Changes

Caution

This was vibecoded. I have done my best to verify the code.

My fix is to track the current window, and in didMoveToWindow check if the movement is from nil to a window, reenabling user interaction if so. This appears to cover the dismiss case.

I am no expert here and I don't trust Claude, so please correct me if I'm wrong, there's a good chance I am. However, this does appear to fix the issue both in my minimal repro and in the main app.
