fix: build configuration and resource fixes for successful APK build 

- Fixed sherpa-onnx dependency to use Maven Central package
- Fixed VoiceIntent enum name conflict with android.content.Intent
- Added AndroidX configuration in gradle.properties
- Added gradle wrapper jar and script
- Added app launcher icons (adaptive icons)
- Fixed drawable tint references
- Added colors.xml resource file
- Downloaded Whisper tiny.en model tokens.txt
- Updated download-models.sh to download tar.bz2 package

Build now produces 141MB debug APK with sherpa-onnx and Whisper model.
