fix(molecule): verify embedded flannel instead of a flannel DaemonSet

- K3s 1.36 runs flannel embedded in the k3s agent rather than as a
  kube-flannel-ds DaemonSet, so the flannel verifier queried a workload
  that no longer exists and failed the verify step
- For the flannel scenarios, assert every node is Ready and that neither
  the Calico nor the Cilium namespace exists
- Drop the now-invalid kube-flannel-ds DaemonSet assertion
