Pull in-estate service images from artifactapi docker-internal (#310)

Move the estate's own service/operator image pulls off the Gitea container registry (git.unkin.net/unkin) to the artifactapi local docker registry (docker-internal), ahead of the git.unkin.net forge migration which disables Gitea's container registry. The images were copied digest-for-digest into docker-internal and pulls verified before this repoint.

- repoint age-api, bind-operator, bind-tsig-api, cephrgw-operator, encapi, logarchiver, pdbmux image pulls to artifactapi.k8s.syd1.au.unkin.net/docker-internal

Deliberately not repointed here: artifactapi's own api/ui images (circular — it can't pull itself from itself), and the almalinux9-* base/CI images (huge, and their per-repo Woodpecker push targets move in a batched follow-up). Forge raw-CRD URLs and git clone sources are unaffected (those stay on the forge).
