[desktop] Fix misaligned output device (#2786)

Builder::BuildWidget previously relied on Qt to handle layout stretching
by implicitly setting each widget to have a stretch of 0. This is very
bad behavior, so to fix this we must set a stretch of 1 on each widget
that's added by the builder

furthermore, default and default_dark did not properly define a min-width or min-height for QComboBox. This caused the platform theme to take over sizing which is NOT GOOD and should basically be avoided always
