fix: v2 - rectangle selection of one node

[maxy-shpfy]

Description

When a single node is selected in the editor, selectNode is now explicitly called with the node's id and type. Previously, single-node selections only cleared the multi-selection state without triggering selectNode, which could leave the editor in an inconsistent selection state.

Test Instructions

1. Open the editor and using Shift+Drag select ONE node (maybe plus edge).
2. Verify that the node becomes properly selected and its properties/details are reflected in the editor panel.
3. Select multiple nodes and confirm multi-selection behavior still works as expected.
4. Deselect all nodes and confirm the editor clears the selection state correctly.
