POS Ticket Without Price

This module extends the Point of Sale receipt screen so cashiers can print a ticket that hides all money information. On the receipt screen a new button labelled "Print Receipt Without Price" appears next to the normal print button.

• The normal receipt stays available and unchanged; the new button prints an alternative version of the same order.
• In the price-free version, product lines show only the product name and the quantity with its unit of measure. Unit prices, line totals, tax lines, the order total, the change due and the payment lines are hidden.
• The module works entirely inside the Point of Sale interface; it does not add any new menu, database model or report.
• It relies on the standard Point of Sale order receipt and receipt screen components (point_of_sale.OrderReceipt and point_of_sale.ReceiptScreen) and adds its own receipt component and screen extension.
• No business rules, checks, automatic computations, emails or scheduled jobs are added; the only behaviour is switching which receipt layout is sent to the printer when the new button is clicked.
