fix: update Android Gradle build configuration

- Update Gradle build tool version to 8.5.2
- Keep Kotlin version at 1.7.10
- Add Android namespace declaration for app module

This change ensures compatibility with latest Android build tools and adds required namespace configuration to comply with Android's package name requirements.
