Add privileged PodSecurity label to 8 namespaces for NetBird router

NetBird router deployments require NET_ADMIN capability, which is
blocked by the default baseline PodSecurity standard. Add
managedNamespaceMetadata with pod-security.kubernetes.io/enforce:
privileged to argocd, frigate, gitlab, grafana, guacamole,
home-assistant, teslamate, and vault ArgoCD Applications.
