Subject: [PATCH] fix: extract images from HTML content at read time for
 existing items

The normalizer fix (1.0.35) only applies to newly ingested items.
Existing items in MongoDB lack photo arrays because dedup prevents
re-processing. Add the same extractImagesFromHtml() fallback in
transformToJf2() so images are extracted from content.html at read
time, making existing xkcd comics and photo posts display immediately.
