Android Physical Device Touch Unresponsiveness Investigation

Bug Summary

On physical Android devices only (not emulator), buttons inside a ScrollView stop responding to taps when the view is scrolled. This is the root cause behind TLON-5436/TLON-5365.

Key constraint: Physical taps involve slight finger movement (2-8px). Emulator clicks have zero movement. The slight movement triggers Android's native touch interception, which steals the touch from JS-based Pressable components before onPress can fire.
