Bind the NRC hoofdObject, recognise a zaken/status/create notification, and key the projection on the zaak (hoofdObject) so the status updates the existing INGEDIEND row to INGESCHREVEN — without reading OpenZaak (§8.1). Retain the ZGW resource in the log (new column + migration) so a rebuild reproduces the approved status. Updates the acceptance fakes for the new IAclClient/IZaakGateway members.
