feat: shopping list pantry hints, barcode multi-API fallback (OPF/beauty/Gemini), README disclaimer
- Shopping list: each item now shows 'Hai già Xg in dispensa' for same-family inventory stock - Lazy-loads inventory once per shopping page visit (_getShoppingInventoryCache) - Matches by first significant token (same logic as related-stock on action page) - Green hint below item badges, dark-mode aware (.shopping-pantry-hint) - Barcode lookup: added Open Products Facts + Open Beauty Facts as step 3; Gemini AI (_barcodeLookupGemini) as final step 4 fallback - Added stockForName PHP endpoint (stock_for_name action) for future use - Restored missing function signatures for _offFetchProduct() and saveProduct() that were accidentally lost when stockForName was added in a previous session - Translation: added shopping.pantry_hint in it/en/de
