feat(event-subscriber): enrich the projection with the zaak reference via the ACL (refs #78)

Browse Source 
On each notification the subscriber reads the zaak's reference (identificatie)
through the ACL — the only code allowed to talk to ZGW (§8.1) — and persists it on
the register_projection row and in the processed_notifications replay log. Storing
it in the log keeps rebuild log-only (ADR-0008): no ACL/ZGW access on rebuild.
