monitoring02: add VictoriaMetrics, vmalert, and Alertmanager ... e329f87b0b

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)

monitoring02: add Caddy reverse proxy for VictoriaMetrics and vmalert ... 4cbaa33475

Add metrics.home.2rjus.net and vmalert.home.2rjus.net CNAMEs with
Caddy TLS termination via internal ACME CA.

Refactors Grafana's Caddy config from configFile to globalConfig +
virtualHosts so both modules can contribute routes to the same
Caddy instance.
