Description

This PR aims to fix the following problem mentioned in Issue #3935: when running the command dms doctor -v and a font that exists in multiple foundries exists it will give out an error and say that the configured font is not in fc-list.

Cause: the problem arises in the fact that in qt qml Qt.fontFamilies() is used while in the go code only the list from fc-list : family is checked and they give out different kind of lists

Fix: in the go code we now build a qt-like font list taking into account the fact that font families may come from different foundries

This PR doesn't aim to solve the other issue mentioned: when a dropdown list has an element that is wider than the given width the elements text will be cut off. The fix lives in dux-qml-common in the following PR: duxlabs-dev/dux-qml-common#33

Claude code was used to generate the code but I take responsibility for it since I have reviewed it, understood it and modified it.
