test: add e2e tests for subgraph promoted widget panel regressions

Add Playwright tests that expose three regressions in the subgraph
promoted widget panel introduced by the proxy-widget-v2 refactor:

- Linked promoted widgets (backed by subgraph input slots) show an
  enabled hide toggle in SubgraphEditor instead of a disabled link icon
- Linked promoted widgets expose Hide/Show input in the WidgetActions
  three-dot menu on the Parameters tab
- Widget labels in SubgraphEditor display raw widget.name instead of
  the renamed label from the subgraph input slot

Also adds data-testid attributes to SubgraphEditor, SubgraphNodeWidget,
and RightSidePanel for stable test selectors.
