feat: Add 16 KB page size support (#3543)

Update build.gradle, adding flexible page sizes flag to support 16 KB devices

Android will force 16 KB page sizes support starting November 1st.

https://developer.android.com/guide/practices/page-sizes

> Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes.

This can already put an application in trouble should it be targeted to Android 15+, when we want to push the APK to the Play Store. The emulators (those that are 16KB ready) are already showing a popup stating that the app isn't 16KB compatible.
