Operating Unit in Purchase Deposit

This module is a small bridge between the operating unit feature and purchase deposits. It does not add new screens or menus; it changes what happens behind the scenes when a deposit is created from a purchase order.

• When a user creates a deposit from a purchase order (through the advance payment wizard), the deposit is now linked to the same operating unit as the purchase order.
• The operating unit is copied automatically from the order, so the user does not have to select it manually on the deposit.
• This keeps purchase deposits consistent with the operating unit used on the related purchase order.

The change is made in the purchase advance payment wizard (purchase.advance.payment.inv), which prepares the values used to create the deposit. The module depends on purchase_operating_unit and purchase_deposit, and installs automatically when both are present. No new fields, menus, reports, checks, emails or scheduled jobs are added by this module.
