feat(react): use favicon on connected source list items

[mrzmyr]

Summary

• Replace the generic SVG icon in the connected sources list with SourceFavicon, rendering the actual site favicon from the source URL
• Match favicon size (20px) to the popular sources list for visual consistency
• Falls back to a BoxIcon when no URL is available or the image fails to load

Before

After

Test plan

• Verify connected sources with a URL show their site favicon
• Verify sources without a URL show the fallback BoxIcon
• Verify favicon size matches the popular sources list icons
