unkin-agent 1169d796e7 grafana: stop pinning the internal CA for Authentik OAuth (#440)
## Why

`identity.unkin.net` moved from an internal `unkin.net` CA-issued cert to the LetsEncrypt `*.unkin.net` wildcard. `auth.generic_oauth`'s `tls_client_ca` pointed Grafana at the internal root only, so the OAuth handshake to the LE-issued cert now fails. Grafana's image trust store already contains the public roots.

## Changes

- Remove `tls_client_ca: /etc/grafana/vault-ca/ca.crt` (and its stale comment) from `auth.generic_oauth`.
- Remove the now-unused `vault-ca-cert` volume and volumeMount from the Grafana pod spec — nothing else in the pod referenced it (the CNPG `endpointCA` reference to `vault-ca-cert` for `s3.ceph.unkin.net` is a separate resource and stays).
- Leave the auth/token/api URLs, scopes and `role_attribute_path` untouched.
