Subject: [PATCH] [FIX] purchase: orderpoint should redirect to linked PO

Since procurement order removal. We lost the behavior
to access PO directly from the orderpoint.
In 10.0 the puchase button redirect to the procurement order
and the purchases were accessible from the procurement order.

We do not have the procurement order anymore thus the button
return to a list view with all RFQ and PO.

Fixes #23096
