UI: Use QCheckBox::toggled signal for checkbox changes

Like in 4f8b17d61, "toggled" is the signal that listens for changes
however they may have happened (including through things like
accessibility software), whereas clicked only is emitted on mouse
clicks. We should react to any kind of change, whatever prompted it.
