fix(library): evict stale thumb URL on image load error, re-observe for retry

Browse source 
When a signed S3 URL expires the img fires onerror. Previously the stale URL
stayed in thumbCache so the broken image would persist. Now we delete the cache
entry, clear the loaded class, and re-add the element to the IntersectionObserver
so the next time it scrolls into view a fresh signed URL is fetched.
