Point of Sale - Hide Banknote Buttons

This module changes the Point of Sale payment screen by hiding the shortcut buttons that add banknote amounts to a cash payment. In standard Odoo, when a cashier pays a cash order, the payment screen shows quick buttons such as +10, +20 and +50 to speed up entering the amount received. After installing this module, those banknote buttons are no longer displayed.

• The change is purely visual: it only affects the Point of Sale interface, not the underlying payment logic.
• No new menus, screens, buttons or reports are added.
• No business rules, checks, computations, default values, restrictions, emails or scheduled jobs are introduced.
• No database models are created or modified; the module only loads a stylesheet into the Point of Sale assets.

The module depends on point_of_sale and targets Odoo 16.0. It is useful for shops whose currency or cash habits do not match the default banknote denominations, or where cashiers prefer to type the exact amount received instead of using preset buttons. Because the change is limited to the payment screen styling, the rest of the Point of Sale workflow — selecting products, validating orders, and registering payments — continues to work exactly as before.
