Mirrors the puppet authoritative `master-zones` view (match-clients `acl-main.unkin.net`, recursion no) — restricting who can query bind-authoritative.
## Changes
- add `auth-acl-main` BindACL with the puppet authoritative acl-main.unkin.net networks (13-17,19,20,24-29)
- `allow-query { auth-acl-main; 10.42.0.0/16; }` on bind-authoritative via extraOptions
## Notes
- Implemented as a global `allow-query` rather than a BindView: dynamic *primary* zones inside a view would need per-view `allow-new-zones` (an operator gap). Functionally equivalent for the single master-zones view.
- `10.42.0.0/16` (pod network) is included so secondaries can SOA-refresh from the primary during catalog replication — without it, replication breaks.
- Works on the current operator (no HOLD).
## Caveat
The DNS Services use externalTrafficPolicy: Cluster, which SNATs external clients to node IPs (198.18.19.x, already in acl-main), so this ACL doesn't truly restrict *external* clients yet. True source-IP restriction needs externalTrafficPolicy: Local — happy to switch if wanted.
