feat(grafana): provision disk alerts to ntfy

Provision Grafana Unified Alerting as code: ntfy webhook contact point (?template=grafana), notification policy tree, and cumulative disk tiers for HDD temperature (48-60C, <20C) plus ZFS/filesystem capacity. Lower the smartctl exporter interval to 30m for alert responsiveness.
