ShipAuthoringStore.ValidateLoaded is the one composition of hull Validate and ValidateProducts;
Read and the draft branch of ship-authoring validate both call it (ValidateProducts is private).
Tests: a draft with an unnamed hull is refused; blank product name and key collision with the
offending product not first (both makers in turn); a negative hull price refused.
Builds untested here; the verify job runs at the end.
