Lower infra-host-ttl (900s → 120s) and tcp-reuse-timeout (60s → 15s)
so unbound recovers faster from upstream TLS forwarder failures
instead of staying stuck after ISP outages.

Configure Unbound to query both ns1 and ns2 for the home.2rjus.net
zone, in addition to local NSD. This provides redundancy during
bootstrap or if local NSD is temporarily unavailable.

Add exporters and scrape targets for services lacking monitoring:
- PostgreSQL: postgres-exporter on pgdb1
- Authelia: native telemetry metrics on auth01
- Unbound: unbound-exporter with remote-control on ns1/ns2
- NATS: HTTP monitoring endpoint on nats1
- OpenBao: telemetry config and Prometheus scrape with token auth
- Systemd: systemd-exporter on all hosts for per-service metrics
Add alert rules for postgres, auth (authelia + lldap), jellyfin,
vault (openbao), plus extend existing nats and unbound rules.
Add Terraform config for Prometheus metrics policy and token. The
token is created via vault_token resource and stored in KV, so no
manual token creation is needed.
