PR #298 added barmanObjectStore WAL archiving to every CNPG cluster, but
litellm, puppet and paperclip run the `17-minimal-trixie` image, which omits
the barman-cloud CLI. Their archiver dies with `exec: "barman-cloud-wal-archive":
executable file not found in $PATH`, so their buckets stay empty.

Switch those three to `17-system-trixie` (the -system variant already used by
the other clusters), which bundles the barman-cloud tools the in-tree backup
mechanism shells out to. This is a rolling image change; CNPG performs it as a
switchover with no data change.

Note: litellm and puppet will only start archiving once the separate stale
vault-ca-cert trust-anchor issue is also fixed (tracked separately) — that
blocks TLS to s3.ceph.unkin.net for all clusters.
