ingest: suppress Google-news shared placeholder image (googleusercontent) -> null -> category cover fallback

Root cause: Google News RSS items carry no enclosures; pipeline fell back to og:image from the news.google.com interstitial, which serves ONE shared Google-branded tile (lh3.googleusercontent.com/J6_coFbo...) for every article. 601 rows shared that URL (maple 243 / finance 358). New image-guard blocks *.googleusercontent.com images at ingest; 16/16 regression tests; prod DBs migrated tile->NULL; images rebuilt technews:10 finance:4 maple-brief:11 and deployed.
Serve article images locally: /images proxy route with SSRF-guarded

+ * Root cause (verified live against the production DBs, 2026-08-18):
+ * Google News RSS search feeds (news.google.com/rss/search?q=...) carry NO
+ * per-article image enclosures (0 enclosures observed across ~300 live
+ * items across three feeds), so the pipeline falls back to reading
+ * og:image from the news.google.com interstitial pages — and Google serves
+ * ONE shared Google-branded note/list tile (lh3.googleusercontent.com/
+ * J6_coFbogxh...) as og:image for every single interstitial. That one URL
+ * was stored verbatim as the article image for hundreds of rows (finance
+ * 358, maple-brief 243), so those cards render an identical "Google
+ * icon" and og:image/social shares point at the same tile.
+ *
+ * In this pipeline the only producer of a *.googleusercontent.com image
+ * URL is that shared placeholder: feed enclosures never carry Google
+ * content, and extractContent's og:image read from a Google page is only
+ * ever the interstitial tile. Blocking the host is therefore safe with
+ * no false positives — a googleusercontent image in our DB is by
+ * definition the shared tile, never a real article photo.
