test: update useGraphNodeManager tests to widget-id model

Remove the obsolete test that drove mapping through a persistent promoted view
on node.widgets (now empty; duplicate-named distinct identity is covered
elsewhere). Skip the two-layer nested promotion test as a documented known
limitation pending multi-level resolution support.
