Only OrRule had a Prefix ("prepended to each found reference", e.g. postal 74 →
D74); the primary search passed "" for prefix, so an award whose references are
D01/D02… couldn't prepend the D on its main rule — only on OR fallbacks. Add
Def.Prefix, pass it into the primary run(), and expose a Prefix input next to the
primary Leading/Trailing fields in the award editor.
