fix: collapse GPU Service menu in Personal Org; add K8s-direct CTA

Two follow-ups to the GPU Service gating:

- In Personal-Org view the access extension was stripping
  canSeeAdmin/canSeeOrgAdmin but leaving canSeeGpuService at its
  admin-shortcut value, so platform admins switched into Personal
  still saw the menu even though Personal scope can't host a K8s
  cluster. Mirror the probe result through sessionStorage so the
  extension can fall back to the strict cluster-availability signal
  in that branch.

- The empty-state CTA now reads 'Add a Kubernetes Cluster' and, on
  click, opens the cluster-create flow with Kubernetes preselected
  via clusterSession.providerHint. ClusterCreate consumes the hint
  on mount: it seeds extraData.provider and starts at the configure
  step instead of the provider catalog, so the user lands one click
  closer to the form they actually need.
