RED: ExpireRegistrationWorker loads the registration a RegistratieVerlopen job correlates to and expires it (idempotent on redelivery, throws on unknown so the job is redelivered); RegistratieVerlopenProcessor drains the parked jobs and completes each, leaving a failing one un-completed (§8.6). Mirrors the OpenZaak and escalation worker/processor pairs. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
