chore: migrate to AGP 9.1.1 and Gradle 9.3.1

- Upgrade AGP from 8.9.3 to 9.1.1 and Gradle wrapper from 8.11.1 to 9.3.1
- Remove de.nanogiants.android-versioning plugin (incompatible with Gradle 9
  due to removed convention API); replace with inline gitVersionCode() using
  providers.exec for the same git rev-list --count HEAD logic
- Fix OpenCV proguard: use proguard-android-optimize.txt (AGP 9 removed
  support for the non-optimize variant)
- Move resValues = true from global gradle.properties into the app module
  buildFeatures block (the global default property is deprecated)
- Remove deprecated gradle.properties options no longer recognized:
  android.sdk.defaultTargetSdkToCompileSdkIfUnset,
  android.enableAppCompileTimeRClass, android.usesSdkInManifest.disallowed,
  android.r8.optimizedResourceShrinking

Remaining deprecated options kept intentionally:
- android.builtInKotlin=false and android.newDsl=false opt out of AGP 9 built-in
  Kotlin support. Removing them requires dropping org.jetbrains.kotlin.android
  from all 100+ modules and migrating to AGP built-in Kotlin compilation —
  planned as a follow-up.
