v1.0.0-rc.41

Fixed

• Settings: long labels next to dropdowns rendered vertically. Some rows like Water → Display Unit were squeezing the label down to a single-character column and stacking it letter by letter. Capped the small-dropdown width so labels render normally again.
• OFF local mirror: scanning a UPC-A barcode no longer makes a pointless call to the public OFF API. Scans now use the same canonical 13-digit format Open Food Facts stores its codes in, so the local mirror hits on the first lookup instead of after a roundtrip.
