feat: Allow Cards selection by clicking anywhere on the card with entireCardClickable property

Description

This change introduces a new property for Cards that allows the entire card to be clickable to make a selection. This is helpful when selection is a main use-case for this instance of Cards, and there are no other interactive elements in the cards sections.
