fix: Improve French price extraction and cookie handling

AI Schema:
- Improve extraction prompt for French e-commerce pages
- Add specific instructions for French price format (comma decimal, space thousands)
- Add French stock status terms (Ajouter au panier, Disponible, etc.)
- Fix price normalization to handle French format:
  - "12,99" -> 12.99
  - "1 234,56" -> 1234.56
  - "1.234,56" -> 1234.56

Scraper Service:
- Add comprehensive cookie/popup selectors for French sites:
  - E.Leclerc, Auchan, Carrefour (OneTrust, Didomi)
  - Cdiscount (#footer_tc_privacy_button_2)
  - Boulanger (.bcom-consent-accept-all)
  - Gifi, Centrakor (Magento cookie buttons)
  - PrestaShop sites (Stokomani, B&M)
- Add common CMP platform selectors
- Add French text-based selectors for cookie acceptance

+**PRICE (IMPORTANT - French format):**
+- French prices use COMMA for decimals: "12,99 €" means 12.99
+- Thousands separator is SPACE or DOT: "1 234,56 €" or "1.234,56 €" means 1234.56
+- Currency symbol is usually € at the end
+- Look for: price tags, "Prix:", "€", numbers near "Ajouter au panier"
+- Extract as DECIMAL NUMBER (convert comma to dot): 12,99 -> 12.99
+- Ignore crossed-out/barré prices (old prices)
+- If multiple prices, take the current/main price (not the original)
 - If unclear: set null and confidence < 0.5
