fix(settings): restore the Other Models master toggle state on load

updateOtherModelsControls() synced the sub-type checkboxes and default-root
selects but never set the master toggle's checked state, and the
setting_toggle macro renders no checked attribute, so after a page refresh
the toggle always appeared off regardless of the saved setting.
