This update streamlines the operation of certified scales in Point of Sale. The previous system's tare management has been removed, consolidating the tare function into the dedicated scale tare button. This simplifies the user experience and ensures accurate weight measurements for certified transactions.

This PR removes the tare managing from Point Of Sale for the certified scales, leaving its management for the scale tare button.
