v1.7.25 — partial throw from banner, barcode fallback, related stock, Bring! re-add fix

- Fix: Bring! items re-appearing after manual removal (missing _markBringPurchased call in removeBringItem / confirmShoppingItemFound; autoAddCriticalItems now respects blocklist for qty=0 items)
- Fix: barcode false 'not found' — new _offFetchProduct() helper tries UPC-A↔EAN-13 candidates × 2 locales with auto-retry; UPCItemDB fallback also iterates candidates
- Fix: bannerThrowAway() now opens partial-throw modal (location + qty input + throw-all button) instead of immediately discarding everything
- Add: related stock card on action page — shows same-family inventory items when scanning a branded product
