Closes #3228: Change featured image to thumbnail image in Marketing Cloud layouts

[danahertzberg]

Description

This PR changes the Marketing Cloud layouts to use the thumbnail image instead of the featured image.

Question: If the thumbnail image is not populated, should we fill it in with the placeholder image or the featured image?
Answer: Need help with populating with featured image if no thumbnail, and placeholder if no featured image.

Release notes

Marketing Cloud layouts now use the Thumbnail Image field for news images, replacing the previously used Featured Image field, and setting the Featured Image field as the fallback.

If the thumbnail image is unavailable, using the featured image as a fallback is best. This ensures that the content remains visually consistent.

Looks good! Potential future improvement: in the "Content for email" admin view, disable links for news layouts with images (Hero, 50/50, etc.) for news nodes that don't have a featured or thumbnail image.
