test(infra): verify-objecten-notifications asserts Objecten publishes to NRC (refs #152)

Registers an abonnement on the `objecten` kanaal pointing at the existing
webhook sink, writes a RegisterRecord exactly as the ACL does on approval, and
waits for the delivery. That is the whole publish chain in one assertion:
Objecten → its celery worker → NRC → nrc-beat → the callback.

Fails today at the first hop, which is the point:

  NRC POST /api/v1/abonnement → 400: {"name":"naam","code":"kanaal_naam",
  "reason":"Kanaal met deze naam bestaat niet."}

Also splits S-19b (#150) into #152/#153 in BACKLOG.md — the notification wiring
and the projection re-source are independently deployable (CLAUDE.md §13).

+# S-19b-1 (#152): verify the Objecten → NRC notification path against an ALREADY-RUNNING full
+# stack. Registers an abonnement on the `objecten` kanaal pointing at a throwaway webhook sink,
+# writes a RegisterRecord object (exactly as the ACL does on approval, S-19a), and asserts the sink
+# receives the notification.
+#
+# This is the whole publish chain in one assertion: Objecten → its celery worker → NRC → nrc-beat →
+# the subscriber callback. S-19a deliberately left it disconnected (ADR-0028); this proves it is
+# connected for real, rather than merely configured.
+#
+# All in-network, reaching services by container IP (a single-label host isn't URL-valid for NRC's
+# callbackUrl validator; the runner can't reach published ports — gitea-actions-gotchas.md §5/§6).
+# EXCEPT Objecten/Objecttypen, which must be reached by SERVICE NAME: Objecttypen echoes the request
+# Host into the objecttype `url` and Objecten only accepts the one matching its configured api_root
+# (ADR-0028).
+#
+# Does NOT manage the stack lifecycle, but cleans up the sink/driver it creates.
