Fix: Disable Qt Android focus highlight in CI

[Splaser]

Summary

Fixes a blue highlight that remains visible on the main screen after opening and closing the search/filter input on Android 8.0 and newer.

Cause

This highlight is not rendered by the Pegasus QML theme. Qt 5.15.10 creates a transparent native QtEditText view to communicate with the Android input method.

When the software keyboard is shown, Qt positions this view over the QML TextInput and requests focus. Hiding the keyboard does not clear the native view's focus, so Android continues drawing its default focus highlight at the previous input position.

Fix

Add a small patch for Qt's Android QtEditText implementation that disables the default focus highlight on API 26 and newer:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O)
    setDefaultFocusHighlightEnabled(false);
