✨ Add automatic sidebar sync with canvas updates

[rabea-al]

Description

This PR introduces automatic synchronization between the Component Preview sidebar and the canvas state.

The sidebar’s Inputs and Outputs sections now update immediately when nodes or links change — such as when connections are added, removed, or modified — without requiring a manual refresh.

Thanks for the PR!
The current way it's implemented, if I understood it correctly, for each small drag it fires the event for the sidebar to listen.
Try firing the event from here:

I updated the canvas update logic so it no longer fires on every tiny drag movement.
Now it waits until the link is actually completed before emitting the update signal.
