bind-internal: add cheeztv.unkin.net record (#421)

why: cheeztv.unkin.net never resolved — external-dns ignores unkin.net (domain-filter is k8s.syd1.au.unkin.net only); *.unkin.net names are DNSRecord CRs.

- add cheeztv-dns-internal A record → 198.18.200.4 (internal traefik VIP serving the cheeztv gateway)
