fix(mobile): APK starts on Android 15+ 16 KB page devices and emulators

On an Android 16 emulator the release APK crashed at launch with
"Cannot read property 'NativeModule' of undefined": libexpo-modules-core.so
was missing for the ABI the device picked. Two build defects:

- librnskia.so was linked with 4 KB segment alignment (Skia 2.0.0-next.4
  lacks ANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES), so 16 KB page devices cannot
  load it; a pnpm patch adds the flag
- the APK carried incomplete x86, x86_64 and armeabi-v7a folders from the
  React Native libraries; an Expo config plugin keeps only arm64-v8a, the ABI
  the native modules are built for (the APK also halves in size)

scripts/check-apk.mjs now fails the release on another ABI, a missing core
library or a library not aligned to 16 KB.
