fix: resolve bugs in ServicesPage, NodesPage, and k8s helpers

- Add missing useEffect dependency array and useCallback for closePanel
- Fix invalid StatusLabel status="" to "info" for non-kube-vip services
- Add ARIA dialog attributes to service detail panel
- Use phaseToStatus() in NodesPage instead of hardcoded Running check
- Remove dead code in getNodeVipLabel (label keys never contain =)
- Simplify redundant lease lookup in OverviewPage
- Fix 46 ESLint indentation warnings
- Add CHANGELOG.md
