chore: 011Y-835 - Update to Android Gradle Plugin 8.3.2 and SDK 34

[agrognetti]

Upgraded Android Gradle Plugin, Gradle wrapper, and dexcount plugin versions. Migrated all modules to use compileSdk 34 and targetSdk 34, added namespace declarations, and updated build configuration to match latest Gradle and Android standards. Improved build script structure and fixed deprecation warnings for Gradle tasks.

Requirements

• I have added test coverage for new or changed functionality
• I have followed the repository's pull request submission guidelines
• I have validated my changes against all supported platform versions

Describe the solution you've provided
Upgrade gradle from 7.3.3 version to 8.5.0

Additional context
I wanted to build the project to check something, but I was asked to upgrade the gradle version to 8.x.x and I thought it was a good idea to push the change.
I haven't tested it extensively since this is out of the scope of my tickets, but it seems to work correctly. @tanderson-ld check it a bit more before approve it please.

Note

Upgrade build system to Gradle 8.5/AGP 8.3.2 and migrate all modules to compile/target SDK 34 with namespace and modern Gradle/Android DSL updates, plus test/proguard tweaks and a receiver fix for Android 13+.

• Build system:
  • Upgrade Gradle wrapper to 8.5, Android Gradle Plugin to 8.3.2, dexcount to 4.0.0, and Nexus Publish plugin to 1.3.0.
  • Refactor root build.gradle: use base.archivesName, centralize Android config via BaseExtension, enable deprecation checks, and add test JVM --add-opens.
• Android SDK/config:
  • Migrate all modules to compileSdk/targetSdk 34, add namespace, switch to new minSdk/compileSdk DSLs, remove buildToolsVersion.
  • Update manifests and activities (add android:exported where needed); switch to new packaging { resources { excludes } } and publishing { singleVariant("release") }.
• Javadoc & publishing:
  • Rewrite Javadoc/sources tasks using lazy task registration; add Android boot classpath and BuildConfig generation deps; update artifact publication to new APIs.
• Testing & dependencies:
  • Bump AndroidX test libraries and orchestrator; add ProGuard rules in example and contract-tests; exclude error_prone_annotations to avoid dexing issues.
• Runtime:
  • On Android 13+, register connectivity BroadcastReceiver with Context.RECEIVER_NOT_EXPORTED in AndroidPlatformState.
