🎨 style: update ModelPricing card with IconLayers and larger icon size

Replace the main card icon in ModelPricing component with IconLayers to better represent the model catalog functionality. Increase icon size from 'large' to 'extra-large' for improved visibility and visual hierarchy.

This change enhances the user interface by using more appropriate iconography and giving the primary navigation elements greater emphasis.
