Node Info sidebar opens generic node list instead of showing selected node's properties

### Description

Clicking "Node Info" on a node opens the sidebar Node Tab with the search bar and full list of all nodes, instead of showing the properties/info of the currently selected node.

### Steps to Reproduce
1. Select a node on the canvas
2. Click "Node Info"
3. Observe the sidebar opens with a generic node search/list rather than the selected node's properties

### Expected Behavior
"Node Info" should display the properties and details of the selected node.

### Actual Behavior
The sidebar opens the Node Tab with a search field and the full list of all available nodes, with no way to view the selected node's properties unless you know its name.
