Valerio a53578e45c fix(extractors): detect AWS WAF verifying-connection page, add OG fallback to ecommerce_product
Two targeted fixes surfaced by the manual extractor smoke test.

cloud::is_bot_protected:
- Trustpilot serves a ~565-byte AWS WAF interstitial with the string
  "Verifying your connection..." and an `interstitial-spinner` div.
  That pattern was not in our detector, so local fetch returned the
  challenge page, JSON-LD parsing found nothing, and the extractor
  emitted a confusing "no Organization/LocalBusiness JSON-LD" error.
- Added the pattern plus a <10KB size gate so real articles that
  happen to mention the phrase aren't misclassified. Two new tests
  cover positive + negative cases.
- With the fix, trustpilot_reviews now correctly escalates via
  smart_fetch_html and returns the clean "Set WEBCLAW_API_KEY"
  actionable error without a key, or cloud-bypassed HTML with one.

ecommerce_product:
- Previously hard-failed when a page had no Product JSON-LD, and
  produced an empty `offers` list when JSON-LD was present but its
  `offers` node was. Many sites (Patagonia-style catalog pages,
  smaller Squarespace stores) ship one or the other of OG / JSON-LD
  but not both with price data.
- Added OG meta-tag fallback that handles:
  * no JSON-LD at all -> build minimal payload from og:title,
    og:image, og:description, product:price:amount,
    product:price:currency, product:availability, product:brand
  * JSON-LD present but offers empty -> augment with an OG-derived
    offer so price comes through
- New `data_source` field: "jsonld", "jsonld+og", or "og_fallback"
  so callers can tell which branch populated the data.
- `has_og_product_signal()` requires og:type=product or a price tag
  so blog posts don't get mis-classified as products.

Tests: 197 passing in webclaw-fetch (6 new), clippy clean.
