fix: FS.com price extraction — DOM-based prices + shipping-context exclusion
- All 247 FS.com prices were €79 (shipping threshold, not product prices) - Root cause: 'Gratis Versand ab 79 € (ohne MwSt.)' banner matched first - Fix 1: DOM price extraction in page.evaluate with bad-parent skip list - Fix 2: bodyText qualified patterns skip matches near shipping keywords - Fix 3: waitForSelector for price DOM element before evaluate - Fix 4: Deleted 247 invalid €79 observations from DB Also included from previous session: - db.ts: set has_image=true on image writes (fix 632 desync rows) - spec-updater.ts: DR/FR/LR/ER/ZR → SMF, SR → MMF fiber type inference

PRICE_QUALIFIED bodyText regex matched this banner text before reaching the actual product price. Fix: (1) DOM-based price extraction added to page.evaluate — targets [class*='price-value']/[class*='product-price'] etc., skipping elements inside shipping/banner/footer parents; (2) bodyText qualified patterns now check 200-char context for versand/shipping/gratis keywords and skip matches that appear in shipping context; (3) waitForSelector for price elements added before evaluate; (4) deleted 247 invalid €79 observations from DB."}
