ux: add "image" card layout

This change to the cards partial adds support for an alternate layout.

The layout to use is decided based on the input parameter used to
generate the card:

- If an `image` is given, the new "tall image" layout is used
- If an `icon` is given, the default layout is used

Image and icon are mutually exclusive.
