Trust the sshca host CA alongside the legacy signer (#530)

Browse Source 
Catalog compilation moved to the k8s puppetserver compilers, which sign host certificates against the terraform-managed `sshca` mount. Clients only trust the legacy `ssh-host-signer` CA, so every re-signed node (ausyd1nxvm2120 already) presents a certificate nothing accepts, and knownhosts emits no plain host-key fallback.

- Add a second `@cert-authority *` entry for the `sshca` public key to `profiles::ssh::knownhosts::lines`.
- Keep the legacy entry untouched so legacy-signed hosts still verify.
