feat: enable sync by default for better testing and UX

- Change default sync preference from false to true in PersistentPreferenceRepository
- Update MainScreenState initial value to reflect sync enabled by default
- Remove complex sync toggle detection from BrowserStack scripts
- Rebuild APK with sync automatically enabled on first launch

This eliminates the BrowserStack toggle detection issues and provides
better user experience with sync enabled by default. No more manual
toggle activation needed for testing!
