feat(hub): monitorización del cluster unibus — dashboard + deploy del exporter

- hub/dashboards/unibus-cluster.json: dashboard 'unibus — Cluster' (carpeta Fleet, datasource VictoriaMetrics): nodos up, cluster_size, nodos caídos, posture homogénea segura, matriz de posture por nodo (enforce/acl/tls/cluster/store-kv), latencia de scrape y tabla de estado por nodo. Panel meta-leader preparado (n/d sin métricas NATS). - hub/deploy_unibus_exporter.sh: compila el exporter, sube binario + CA del cluster a magnus e instala el servicio systemd apuntando a la VictoriaMetrics local. El exporter (apps/unibus_exporter, sub-repo Gitea propio) compone parse_unibus_health + format_prom_exposition + push_prom_remote del registry.
