In this commit, we just copy/move the files.
In next commit, delete the part of each file
that is not related to its model.

Part-of: odoo/odoo#116165
Before this commit, when the user is in the project update kanban view
and click on Purchase Order row shown in Project Profitability section
in the right side panel, the user cannot create or edit a purchase order
because the AA on each purchase order line is used to link those
purchase orders to the project.
This commit adds the project and also `project_update` key in the
context to use them keys to set the AA on new Purchase Order Line by
default.
