Add toggle to quickly show the "before" of a LTN

When doing a presentation it would be useful to be able to quickly show the current state, before any restrictions.

I tried to create a new neighborhood with the same limits in the same project, but the restrictions are already applied to it.

I guess creating a different project would work, but it's not convenient to switch from one to the other.

Look for UI components that handle toggles or state visibility in the frontend code. The feature likely involves adding a button or switch to toggle between the current restricted view and the original 'before' state. Check how neighborhood data and restrictions are loaded and applied. Start by exploring the presentation mode or view controls to understand where to integrate this toggle.
