feat: initial kube-vip Headlamp plugin

Headlamp plugin providing visibility into kube-vip virtual IP and load balancer deployments. Features: - Overview dashboard with deployment status, VIP mode, leader election - Services page with LoadBalancer VIP assignments and detail panels - Nodes page showing kube-vip pod status and leader designation - Configuration page with DaemonSet config, IP pools, leases - Service detail section injected into native Headlamp Service views Read-only plugin — no cluster write operations. Uses standard K8s resources (no CRDs): Services, Nodes, Pods, DaemonSets, Leases, ConfigMaps with kube-vip.io/* annotations. 74 tests across 7 test files. All tsc/lint/format/test checks pass.
