🛠️ Migrate Android build to AGP 9 (Gradle 9.7.1, AGP 9.4.1)

[Friedinger]

Summary

Mirrors the AGP 9 migration done for flutter-workflow's test_app in RubberDuckCrew/flutter-workflow#86, using the toolchain versions currently on that app's main branch (which tracks the latest supported versions via Renovate) rather than the exact versions pinned in that PR.

• AGP: 8.13.2 → 9.4.1 (android/settings.gradle.kts) — required to run under Gradle ≥ 9.6; matches flutter-workflow test_app's current AGP version.
• Gradle: 9.5.1 → 9.7.1 (wrapper).
• android/app/build.gradle.kts: removed kotlin-android (AGP 9 forbids applying it directly) and added buildFeatures { resValues = true } (needed since GitDone sets app_name per product flavor via resValue).
• android/gradle.properties: added android.newDsl=false + android.builtInKotlin=false — same flags used by the Flutter AGP 9 template for legacy DSL/KGP setups.
• Kotlin Gradle plugin (2.4.20), Flutter (3.47.5) and the analysis_options.yaml analyzer excludes were already at the versions used by flutter-workflow test_app's main branch, so no change was needed there.
• Pub dependencies were left untouched — kept current via Renovate.

Walkthrough

The Android application plugin version and Gradle wrapper version were updated. The app build configuration and Gradle properties were also changed.

Changes

Android Gradle configuration

Layer / File(s)	Summary
Gradle toolchain and app configuration android/settings.gradle.kts, android/gradle/wrapper/gradle-wrapper.properties, android/gradle.properties, android/app/build.gradle.kts	The Android application plugin version changes from 8.13.2 to 9.4.1, and the Gradle wrapper version changes from 9.5.1 to 9.7.1. Gradle properties disable the new Android DSL and built-in Kotlin support. The app build removes the direct kotlin-android plugin declaration and enables resource values.

The Android app may fail to build or launch because its main activity is no longer compiled. Restore Kotlin compilation before merging.

Resource values join the build,
Kotlin's direct plugin line is stilled.
