Summary

This PR introduces drag-and-drop functionality to the Select Answers component in the form builder, enabling users to rearrange their selected answers to match their preferred display order.

Key changes include:

• Integration of react-beautiful-dnd components (DragDropContext, Droppable, Draggable) to manage drag events.
• Implementation of the handleDragEnd function to update the answer order based on user interaction.
• Use of a DraggablePortal to render the dragged element at the document body level, resolving offset issues caused by CSS transforms in modal containers.
• Minor updates to state management to ensure the new order is immediately reflected.

@NethmiRodrigo and @denniskigen needs review..!

[Bharath-K-Shetty]

Hey @NethmiRodrigo, could you please clarify if we should implement a cloning approach so that the original answer item remains visible in the list while dragging, or is it acceptable that the item is temporarily removed from its position and only appears in the drag layer until dropped?

Thanks @Bharath-K-Shetty! I know this is a large ask, but is it possible to reuse the functionality that we have that enables dragging questions in the interactive builder:

It's okay if we would have to change the appearance of the answers from the blue tags to something like above. Its best if we can minimize the use of third party libraries. We already use a couple and I'd like to minimize the use as much as possible to keep the build dize small.
