feat: use correct Google Play API endpoints for APK download

- Use generatedapks.list to get downloadId from APK manifest
- Use generatedapks.download to fetch binary APK with downloadId
- Improve universal APK detection with better targeting logic
- Add detailed logging for debugging APK selection

Based on correct API documentation:
- GET /applications/{packageName}/generatedApks/{versionCode}
- GET /applications/{packageName}/generatedApks/{versionCode}/downloads/{downloadId}:download
