Update Android project configuration and permissions

- Added new entries to .gitignore to exclude Android build artifacts and keystore files.
- Updated build.gradle files to include Kotlin Gradle plugin dependencies.
- Enhanced gradle.properties with JVM arguments for better performance.
- Modified AndroidManifest.xml to include additional permissions for network and location access.
- Refactored package names in several classes to use a new namespace.
- Removed deprecated LogActivity, SelectedApplicationsActivity, SettingsActivity, and TrustedCertificatesActivity.
- Introduced a new scheduling mechanism in the Scheduler class to handle exact alarms on Android 13+.
- Updated MainActivity to integrate new UI components.

These changes improve the overall structure and functionality of the Android application.
