Subject: [IMP] point_of_sale,pos_*: allow users to manage orders in the pos
 frontend

We now allow invoicing of finalized orders in an open session in this first
iteration of order management in the pos frontend. Additionally, receipt
reprinting is also introduced. With this feature, we can now reprint the
receipt of old orders.
