[ADD] sale_purchase_stock: link between PO<->SO in case of MTO

In order to improve the navigation between of SO and PO in the case of
MTO, add a direct link between PO<->SO. When the SO is confirmed
(with storable product(s) with MTO + buy),
PO is/are generated, in this case, add a stat button on each model form
to avoid to manually search the related SO with the source field (name).
