test(measurements,whoop): the workout fall-through test reaches its path again

Ladder reconciliation ranks every enum source, so the unranked
fall-through needs out-of-enum fixtures now; a stored single-source
ladder resolving one canonical row is pinned as the new contract. The
body-sync test sheds the import its retired weight path used.
