feat(dependencies): upgrade supported cluster components

- Bump K3s to v1.36.2+k3s1, Calico to v3.32.1, Cilium to v1.20.0,
  kube-vip to v1.2.2, kube-vip cloud provider to v0.0.12, and MetalLB to
  v0.16.0 across sample inventory, role defaults, and argument specs
- Pin the Cilium CLI with a new cilium_cli_tag (v0.19.7) instead of the
  floating stable.txt lookup
- Replace the CiliumBGPPeeringPolicy v2alpha1 BGP template with the
  v2 CiliumBGPClusterConfig, CiliumBGPPeerConfig, CiliumBGPAdvertisement,
  and CiliumLoadBalancerIPPool resource set
- Move Cilium load balancer Helm keys from bpf.loadBalancer to the valid
  top-level loadBalancer path
- Add preflight schema validation and remove the deprecated policy after
  the v2 objects are accepted
- Wait for cilium status after installation
- Pin kube-vip RBAC in a repository template instead of fetching a
  mutable URL, and include EndpointSlice permissions
- Fix the kube-vip bgppeers format to address:ASN comma-separated peers
- Fail clearly when the MetalLB speaker tag replacement does not apply
- Drop the obsolete MetalLB webhook service name version branch
