- Stop camera scanner (stopScanning) BEFORE making the API call in
handleBarcode — active camera stream on mobile browsers can throttle
concurrent fetch requests, causing the lookup to hang indefinitely
- Add 15s AbortController timeout to the api() wrapper so any network
issue shows 'Request timed out — check your connection' instead of
hanging forever on 'looking up...'
- Both fixes together ensure the barcode lookup never hangs
