This update adds a convenient button to payruns that allows users to instantly print a test copy of their payslips. Previously, users had to manually select all payslips and navigate through the system to print a test. This streamlines the process and ensures accurate printing before generating final payslips.

-Originally, the user has to manually select all payslips and then navigate to cog menu to print the payslips.
-Currently, a button has been added to allow for test printing at the payrun.

This update simplifies the point-of-sale refund process by removing the refund button from the action menu. This change prevents unintended refund actions and streamlines the user experience. The change was driven by a community contribution and a related task.

Removed the refund button from the action menu, so this override will never be called
