Sale purchase stock auto confirm

This module gives companies an option to skip the manual step of confirming purchase orders that Odoo creates automatically from sales orders.

Where it appears: - A new setting called "POs Auto Validation" is added to the Sales settings screen, inside a "Purchase stock" block. - The same option is stored on the company, so it can be set per company.

What it does: - When a sales order is confirmed, Odoo looks at the purchase orders linked to it (the ones generated by the Make To Order or Dropship rules). - If the company has the option enabled, any of those purchase orders that are still in draft state are confirmed automatically. - If the option is off, nothing changes and users confirm purchase orders as usual.

Business rules and behaviour: - The automatic confirmation only applies to draft purchase orders belonging to a company where the setting is enabled. - It runs as part of the normal sales order confirmation process, so no extra button or manual action is needed.

Areas touched: - Sales settings (res.config.settings), company settings (res.company) and the sales order confirmation logic (sale.order). - It relies on the purchase orders linked to the sales order, which come from the sale_purchase_stock module.
