366bbb0bed
Phase 1 of the dashboard triage.
Deleted (no current data source, no plan to wire one):
- unifi-overview (unpoller removed after UDM crash)
- caddy-overview (Caddy retired 2026-05-09)
- docker-overview (Docker host era done; workloads on K8s)
- log-explorer (legacy host log shipping not in scope)
- dns-overview (dns-servers job lives but a dedicated dashboard isn't worth keeping; Explore tab covers ad-hoc)
Repointed datasource from `prometheus-legacy` to `prometheus` (the
legacy LXC 227 Prom is retired):
- node-overview, node-metrics — show K8s nodes only (legacy host
node-exporters were never re-scraped post-migration)
- infrastructure-overview — generic up{} + node_* metrics work on K8s
- proxmox-cluster — pve-exporter is now in-cluster (commit 33b452a)
Also deletes DASHBOARD-MIGRATION.md (the migration cut-over completed
with VM 109 retirement on 2026-05-09).
