Point of Sale now shows the full employee list when multiple employees share the same PIN, instead of limiting the choices to matching PIN holders. This makes cashier selection clearer while still logging in only the employee whose selected record matches the entered PIN.

Before if two employees have the same pin, the list of employees was only displaying all employees with the same pin. Now, the list is displaying all employees.

If the user click on a employee with the right pin, it will be logged. Otherwise we close the popup.

The master branch release version has been updated to 18.1 alpha. This prepares the codebase for the next development cycle and helps teams clearly identify builds from this upcoming release stream.

Several labels and fields in the Belgian salary configurator can now be translated. This makes the tool easier to use for employees and administrators working in different languages.

When users create a sales order line from a helpdesk ticket, the product form now prevents choosing a non-service product type. This reduces mistakes and keeps the workflow aligned with services that can be billed from helpdesk work.

When creating a SOL on the fly within a helpdesk ticket, users can also create or edit products. To avoid errors from selecting non-service products, the type field is now hidden in the product form during this process, ensuring only service products are created.

Subscription quote PDFs now show the subscription start date when it is available. This gives customers clearer information about when their subscription begins and helps reduce follow-up questions during the sales process.

Before this commit, the PDF of a subscription quote did not show the subscription start date to customers.

With this commit, the subscription start date will be included in the quote report if it is available.

==================
The kitchen display now supports float quantities, accurately reflecting partial quantities from the POS.
