fix(dependencies): address PR review findings

- Read the MetalLB speaker tag check from the managed host with slurp
  instead of a controller-side file lookup, and match the full image
  reference
- Restore the tigera-operator namespace on the Calico operator Deployment
  wait while keeping the managed CRD waits cluster-scoped
- Make Molecule verify inputs durable and scenario-specific via a
  per-scenario verify-vars.yml, driven by explicit verify_cni/verify_lb
  values instead of non-persisted converge facts
- Rename the kube-vip multi-peer BGP env var from bgppeers to bgp_peers
  and vip_cidr to vip_subnet so v1.2.2 actually reads them
- Map the legacy Cilium routed mode to tunnel and stop passing the alias
  directly to the chart
- Use return-code based failed_when on apply and preflight commands so
  non-error failures are no longer treated as success
- Clarify the sequential K3s upgrade path and backups in the README
- Add kube-vip and MetalLB regression tests and a Cilium mode mapping unit
