fix(secrets): registration and hub mapping share the UsesGrpcHub predicate (review Important)

Browse Source 
AddScadaBridgeSecrets now branches on UsesGrpcHub instead of re-deriving the
same condition, so the doc's single-predicate claim is enforced rather than
aspirational; the role split is a switch with a default-throw so a future
third role must choose its hub half explicitly.
