Adds the operator workstation (10.10.12.200, wireguard) to the resolver
acl-main.unkin.net so it can use bind-resolvers (198.18.200.7) for recursive
lookups. Also lists the router (198.18.21.160) explicitly for documentation;
it is already covered by the existing 198.18.21.160/27 and 198.18.21.0/24.
## Why
`dig google.com @198.18.200.7` was refused: the resolver never set allow-recursion, so BIND defaulted to localnets/localhost. This mirrors the puppet resolver (/etc/named/views.conf + acls.conf) exactly.
## Changes
- `openforwarder` BindView: `match-clients` = the 4 internal ACLs, recursion yes, allow-recursion/allow-query `any` (match-clients gates)
- 4 BindACLs from puppet acls.conf (acl-main.unkin.net/acl-dmz/acl-common/acl-nomad-jobs)
- 26 conditional forward zones in the view (unkin→198.18.19.15, consul→.14, k8s→.20, dmz/network/prod + 10.10.x reverse → 10.10.16.32/33)
- global forwarders 8.8.8.8/1.1.1.1
- operator image → v0.1.4
## Note
Forward-zone upstreams point at the **puppet anycast** servers (still authoritative during migration); flip to the in-cluster authoritative/externaldns LBs once zone data is migrated.
## Validated
kustomize build (59 docs), kubeconform clean.
