feat(acl): set and read the zaak identificatie as the citizen reference (refs #78)

Browse Source 
The ACL now writes the domain registrationId as the zaak's identificatie on
POST /zaken, and exposes GET-through POST /zaken/reference to read a zaak's
identificatie back. Only the ACL touches ZGW (§8.1); the reference is the single
value shown on both the self-service confirmation and the openbaar register.
