Post-cutover verification (argocd-apps#288) found the reverse zone 200.18.198.in-addr.arpa empty: external-dns only writes PTRs when --rfc2136-create-ptr is set, and nothing else feeds that zone. Reverse resolution for the k8s LB range was already absent for clients pre-migration (no forwarder existed), so this completes the reverse path rather than fixing a regression.
- Adds --rfc2136-create-ptr to the external-dns rfc2136 args
Verification after merge: dig -x 198.18.200.2 @198.18.200.7 returns puppetca.k8s.syd1.au.unkin.net (allow a reconcile cycle + negative-cache expiry).
