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.
