Set up the core metrics stack on monitoring02 as Phase 2 of the
monitoring migration. VictoriaMetrics replaces Prometheus with
identical scrape configs (22 jobs including auto-generated targets).
- VictoriaMetrics with 3-month retention and all scrape configs
- vmalert evaluating existing rules.yml (notifier disabled)
- Alertmanager with same routing config (no alerts during parallel op)
- Grafana datasources updated: local VictoriaMetrics as default
- Static user override for credential file access (OpenBao, Apiary)

- auth-system-replacement.md: Mark OAuth2 client (Grafana) as completed,
document key findings (PKCE, attribute paths, user requirements)
- monitoring-migration-victoriametrics.md: Note Grafana deployment on
monitoring02 with Kanidm OIDC as test instance

host with parallel operation, declarative Grafana dashboards, and CNAME-based
