Stunner - Add tooltip for Initial node

Users do not understand how to interact with editors.

The solution is partially implemented on RHPAM-2318

Initial node tooltip needs to be redesigned and implemented.

Original Marvel Prototype

[DRAFT] Acceptance criteria

• When a node is first added to the canvas, it is selected by default. A tooltip prompt is shown, describing how to interact with the toolbox icons to the right of the node.
• The tooltip will only appear after the first node is placed on the canvas, but not after that.
• The tooltip prompt remains visible until the user interacts with the toolbox icons. If they move or resize the node, the tooltip remains visible and remains anchored to the node.
