test(workflow): diploma routing — acceptance + live foreign→CBGV path (S-13, refs #14)

Gherkin scenarios assert the submit carries the diploma origin (domestic/foreign)
into the process. verify-domain now submits a foreign registration and asserts it
parks at CBGVAdvies before Beoordelen, completes CBGV, then advances to Beoordelen
— exercising both DMN branches through the engine (the domestic DIRECT path is the
first registration already parking straight at Beoordelen).
