Entity.SchematicRows(subject) owns which weapon rows a schematic shows, each row's item and
claimed design, and its range (own ship: live; any other: the claimed design's rated range).
SchematicDisplay renders SchematicRow and decides nothing. Headless tests cover default-to-truth,
a weapon claimed as another weapon, a weapon claimed as a non-weapon, own rows, and the rebuild key.
Builds on the Shared side not yet verified at this commit.
