The card documentation needs updates to reflect new restrictions and fix display issues.

✅ What to do

• Remove the "Show Image" and "Image Position" controls from the documentation: card with images are documented as teaser cards
• Remove the "Palettes", "Custom Content", and "List Interactive" examples.
• Fix the horizontal scrollbar issue in the card example so it displays correctly without overflow.
• Update action buttons and links to match the example in Figma: links have an arrow and buttons are 100% wide.
