fix: exclude reanimated/worklets native build, disable New Architecture

react-native.config.js excludes react-native-reanimated and
react-native-worklets from Android native linking — neither is used in
the app and react-native-gesture-handler has a dedicated noreanimated
codepath for exactly this case.

build-apk.sh step 4.6 forces newArchEnabled=false in gradle.properties
after expo prebuild, as a fallback for New Architecture init issues
on Android 15.
