og:image extraction rejected any URL containing "branded_news" as a generic share
image, but that's BBC's normal CDN path for real article photos. So every BBC hero
fell back to the 240px RSS thumbnail (blurry when shown large). Drop that marker;
keep the genuine placeholder markers (facebook-default, og-default, etc.). Updated
the test to assert BBC branded_news paths pass through. 99 tests pass.
(One-time: cleared image_checked_at on the 57 previously-checked articles and
re-enriched recent briefs so existing thumbnails upgrade to og:images.)
