Loads the registration, asks the ACL to set its zaak's final status (new IAclClient.ApproveZaakAsync → POST /statussen), then advances the aggregate to INGESCHREVEN. Idempotent: a repeated approval is a no-op. Adds HTTP-adapter tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
