The rook plugin E2E workflow was calling the reusable plugin-e2e workflow
without the required plugin-name input. This caused the ConfigMap naming
and mount path to fall back to the headlamp-kube-vip defaults, breaking
E2E runs for the rook plugin.
Fix: pass plugin-name: rook to the reusable workflow.
The 'Storage Classes' link is nested under the Rook sidebar button, not
at the top level. Expand the Rook section before asserting visibility.
Also uses /rook/i case-insensitive regex and waits for the plugins list
to render before searching.
