Authoritative zones: accept puppet client dynamic updates (#244)

Browse Source 
Enables per-host RFC2136 updates from puppet (puppet-prod #475 profiles::dns::updater) to the bind-authoritative zones, via the .9 write endpoint.

## Changes
- add **client-update** BindTSIGKey (clusterRef bind-authoritative; operator generates the material into Secret client-update-tsig)
- set `dynamicUpdate: true` + `updateKeyRef: client-update` on all **18** authoritative zones → the operator renders `allow-update { key "client-update"; }`

## Key bridge (manual, per the TSIG plan)
The operator generates the client-update key value; it must reach puppet eyaml (`profiles::dns::updater::key_secret`) for clients to authenticate — until the planned Vault-sync/secret-reflection operator features exist. Get it with:
`kubectl -n bind-internal get secret client-update-tsig -o jsonpath='{.data.secret}' | base64 -d`

## Validated
kustomize build + kubeconform.
