"""
One-time sync of Repository.force_push_allowed from each git repo's own config.
Repos predating the force-push toggle have no force_push_allowed recorded, while their
receive.denyNonFastForwards may already be true, false, or unset. This reads each repo and
stores what it actually permits, so the admin UI and menu label agree with reality.
Reads git; writes only Mongo. No repo's behaviour changes.
