The Point of Sale ticket screen now uses the standard double-click behavior to reopen orders for editing. This reduces custom handling behind the scenes, making the feature easier to maintain and less prone to errors without changing the user workflow.

In the ticket screen the user has the option to double click on an
    order in order to continue editing it. This functionality is implemented
    using custom code for handling the double click. This is cumbersome and
    error prone.
In this PR we replace the custom double click logic with the default
    `t-on-dblclick` from `owl`.
