The sort choice is now written through writeUiPref and both keys are registered
as portable, so they travel with a copied data/ folder like every other UI
preference.
Registering them is the part that matters: writeUiPref stores to the DB, but
only keys on the portable list are read BACK at startup. A key written and never
restored looks exactly like one that was never saved — which is what would have
happened here.
The grey-line toggle had the same gap. It called writeUiPref from the day it was
written but was never added to the list, so it came back off on the next launch.
Found while adding the award keys beside it.
