Describe the Bug

Some Helpful Links in the Knowledge Center do not display their respective favicons as the thumbnail for their cards. Additionally, when a favicon fails to load, the default UnlockEd icon (Unlocked Labs logo) is not being used as a fallback.

To Reproduce

1. Go to the Knowledge Center > Helpful Links tab.
2. Scroll to the following links:
   • 211 Maine
   • Concord Coach
   • Cyr Bus Line
   • Monster.com
   • Recovery Connections of Maine
   • Workforcesolutionsme
3. Observe that the favicon does not appear as the thumbnail for these Helpful Link cards.
4. If the favicon is missing, the card should fall back to displaying the default UnlockEd icon, but it does not.

Expected Behavior

• Each Helpful Link card should display the website’s favicon as its thumbnail.
• If the favicon fails to load, the default UnlockEd icon should be used as the thumbnail instead.

Potential Fixes to Investigate

• Ensure the application correctly retrieves and sets the favicon URL as the card thumbnail.
• If the favicon URL is a relative path (e.g., /favicon.ico), prepend the site's domain to construct a full URL.
• If the favicon fails to load (or is not present in the site’s metadata), fallback to displaying the default UnlockEd icon.
• Ensure the frontend logic properly updates the card thumbnails after a failed favicon fetch.
