Target Android 16 (API level 36)

Google Play rejects app updates that target below API 36 after Aug 30, 2026.

Bumping compileSdk and targetSdk to 36 is the whole compliance change, but
API 36 also enables predictive back by default, and Android then stops
calling onBackPressed or dispatching KEYCODE_BACK. React Native 0.79's
ReactActivity only overrides onBackPressed and registers no
OnBackInvokedCallback, so every BackHandler listener would go dead:
react-navigation's back handling, EdgeModal dismissal, and the
useBackButtonToast exit guard. Opt out of predictive back to keep the back
button behaving as it does today.

React Native 0.86 ships an OnBackPressedCallback shim for this and moves to
AGP 8.12, so both the opt-out and the compileSdk warning suppression come
back out with that upgrade.

 ## Unreleased (develop)
 
 - added: "-m" tag on the version number in the Help scene for Maestro test builds
+- changed: Target Android 16 (API level 36), which Google Play requires for app updates submitted after Aug 30, 2026. Predictive back is opted out of for now, since React Native 0.79 cannot handle it, so the back button behaves exactly as it did before.
 - changed: Style the entire "Already have an account? Sign in" line in the getting-started USP carousel with the tertiary link color, not just "Sign in".
 - changed: Refresh the buy, sell, sort, scan-QR and FIO names icons to the updated design.
 - changed: Use a custom chart icon for the side menu Markets row, so it matches the rest of the menu.
