unkin-agent 757ae5b240 Add a VictoriaLogs cluster and point logs-ingest at it (#488)
The k8s log pipeline stores to ClickHouse via NATS+vector, while the VM estate ships journald to a separate puppet-managed VictoriaLogs cluster. Consolidating on VictoriaLogs in-cluster collapses the two paths, and the logs-ingest gateway has no clients yet so it can be repointed now, ahead of the puppet change.

- add VLCluster `logs` at v1.52.0 (2 vlinsert, 2 vlselect, 3 vlstorage, 180d retention, 250Gi each on cephrbd-fast-delete)
- cap vlstorage disk use at 220GiB per node so 180d stays time-based rather than disk-bound
- repoint the logs-ingest HTTPRoute at `vlinsert-logs:9481`
- add a VictoriaLogs Grafana datasource and install its plugin

Nothing is removed here; NATS, ClickHouse, vector, logarchiver and logviewer keep running until a follow-up drops them.
