This update reorganizes spreadsheet-related code so it can be separated from the Documents app in a future release. For users, there should be little immediate visible change, but it helps make spreadsheet features more flexible and easier to maintain going forward.

The mobile barcode app was updated to work with Odoo's newer barcode handling system after the older method was removed. This should keep barcode scanning reliable on mobile devices and avoid unwanted keyboard or search focus behavior that could interfere with scanning.

The old BarcodeEvents has been removed, this commit updates the code to
use the barcode service instead.
