fix(VE-5061): add observer to observe cslp of selected element

[srinad007]

Title: Added focus element observer to observe the focused element's data-cslp attribute and re-evaluate handleBuilderInteraction every time it changes.

Summary: This PR introduces a MutationObserver to monitor changes to the data-cslp attribute of the focused element. When the data-cslp attribute changes, the handleBuilderInteraction function is re-evaluated to ensure the focussed Toolbar update

Changes:

Added a MutationObserver to the handleBuilderInteraction function.
The observer watches for changes to the data-cslp attribute of the focused element.
When a change is detected, the observer disconnects itself and re-calls handleBuilderInteraction with the reEvaluate parameter set to true.
The observer is stored in the global state and properly disconnected when no longer needed.
