jakman85andClaude Opus 4.8 317b3f02f1 feat(vms): onboard UniFi OS Server as a KubeVirt VM on a non-gating track
First KubeVirt VM app + first real CDI http import. UniFi OS Server (UOS) is
Ubiquiti's current self-host product (the .deb is deprecated); it bundles UniFi
OS + Network app + its own datastore, so no MongoDB companion.

- apps/vms/unifi: CDI DataVolume (Ubuntu 24.04 cloud image -> longhorn-vm
  RWX/Block, live-migratable) + VirtualMachine (evictionStrategy: LiveMigrate)
  with cloud-init that installs podman/slirp4netns/jq and runs the UOS installer
  NON-INTERACTIVELY. The installer URL is resolved at boot from Ubiquiti's public
  firmware API (fw-update.ui.com/api/firmware-latest) — always-latest, no pinned
  URL to maintain (currently UOS v5.1.37).
- L4 exposure: two LoadBalancer Services (TCP+UDP) sharing a pinned, L2-announced
  Cilium VIP 192.168.1.54 (device inform/adoption + STUN can't ride the L7
  Gateway); external-dns publishes unifi.home.keithjackson.dev. UI on :11443.
- default-deny + additive CNPs (controller ingress, egress, and CDI-importer
  egress for the image pull).
- clusters/base/apps-vms.yaml: NON-GATING Flux Kustomization (wait:false,
  dependsOn platform-config) — VMs are a separate lifecycle from the app waves,
  so a slow VM import/install can't stall the app tier.

# Default-deny baseline (R-NET-01): deny all ingress + egress, allow ONLY DNS to the
# in-cluster resolver. Identical shape to the rendered pihole/app baseline. The VM's
# datapath egresses via the virt-launcher pod netns, so this podSelector:{} policy
# governs the VM exactly as it governs a pod (proven by the vm-default-deny test).
# The specific ingress/egress ALLOWS the controller needs are added additively by the
# CiliumNetworkPolicies in 40-networkpolicy.yaml.
