[IMP] point_of_sale: access customer's orders

In the pos one might often need to see the orders of a specific customer.
In order to accomplish this, a pos user would need to search for the
customer's name in the orders screen.

In order to simplify the flow, this PR introduces a new button on the
customer's page that can be used to navigate directly to the orders page
with the customer's name prefilled in the search bar.
