[FIX] point_of_sale: improved GS1 Barcode Recognition for PoS

Before this commit, when a regular barcode, like '3700000000370', which
could be interpreted using GS1 rules, was scanned in PoS, it was
incorrectly identified as a GS1 barcode even though it didn't contain
a product reference. This commit addresses this issue by implementing
a validation check during barcode scanning. The system now verifies
whether a scanned barcode conforms to GS1 rules and contains a product
reference. This ensures accurate barcode recognition.
