## Why
The halb publishes service CNAMEs (`git.unkin.net`, `dashboard.ceph.unkin.net`, and every other halb-fronted name) with a **bare target label**, e.g.:
```
git.unkin.net. 300 IN CNAME au-syd1-prod-halb-vrrp.
```
`dns-updater` builds the RR with `dns.NewRR` and **no $ORIGIN**, so a bare value becomes root-absolute (`au-syd1-prod-halb-vrrp.`) and dead-ends in NXDOMAIN. Once the k8s bind became authoritative for these zones, that broke resolution of every halb-fronted service (git, the Ceph dashboard, ...). `au-syd1-prod-halb-vrrp.unkin.net` / `.main.unkin.net` resolve fine (198.18.19.17) — only the CNAME target was truncated.
## Change (`site/profiles/manifests/haproxy/dns.pp`)
Emit **fully-qualified** CNAME targets (trailing dot), the FQDN form `dns-updater` expects (per its own test fixture `au-syd1-prod-halb.main.unkin.net.`):
- vrrp cnames: `${location_environment}-halb-vrrp.${domain}.`
- non-vrrp cnames: `${location_environment}-halb.${domain}.`
The matching A records are already published in `main.unkin.net`/`unkin.net` just above, so the targets resolve to the VIP.
