ceph/rgw: add s3.ceph.unkin.net to radosgw cert SAN + nginx aliases (#487)

Browse Source 
## Why

`s3.ceph.unkin.net` is the RGW S3 endpoint name used by cephrgw-operator consumers. A companion argocd-apps PR adds it as a CNAME to `radosgw.service.consul`. The radosgw hosts front RGW with nginx (443 -> radosgw:7480) using the vault-issued cert, so **both** the certificate and nginx must recognise the name.

## Changes (hieradata/roles/infra/ceph/rgw.yaml)

- Add `s3.ceph.unkin.net` to `profiles::pki::vault::alt_names` — puts the name in the radosgw cert SAN (renewal re-triggers on the alt-names change).
- Add `s3.ceph.unkin.net` to `profiles::nginx::simpleproxy::nginx_aliases` — nginx answers for that server_name.

### nginx: yes, needed

radosgw sits behind `profiles::nginx::simpleproxy` (listens 443, proxies to :7480) sharing the same vault cert, so the alias is required for nginx to serve the hostname — not just the cert SAN.
