fix(ship-measure): the selection preflight accepts name-mode cases

A case registered beside others in its file lists its trial shard as
<file>#<id>~t1, not <file> (trial 1), so the preflight refused every
name-mode case (for example ship-exploratory-late-input) before any paid
trial. Accept both forms.
