feat(domain): withdrawal cancels the registratie process via a BPMN message event (refs #12)

Add an interrupting message boundary event (RegistratieIngetrokken) on the Beoordelen task that

ends the process; the Workflow Client delivers the message to the task's execution, and the

withdraw handler triggers it best-effort after the domain transition (ADR-0014).
