feat(openzaak): real notification delivery to the BFF webhook (WP-58)

OpenZaak doesn't serve the Notificaties API itself (it's a separate app,
open-notificaties) — standing one up for a real abonnement would triple
this harness for a benefit it doesn't need (exactly one subscriber, this
repo's own BFF). Instead, an opt-in compose overlay adds a celery worker
and points OpenZaak's NotificationsConfig straight at the BFF's webhook
via a zgw_consumers Service; bootstrap-notificaties.sh configures it
idempotently and verify-notificatie.sh proves a real write delivers to
the BFF's audit trail end-to-end.

Verified live: preflight proves the webhook's shared-secret gate both
ways (204/401), a zaak PATCH triggers real celery delivery, and rerunning
both scripts against an already-configured harness stays idempotent.
