This change updates Enterprise modules to work with the new invoice processing approach in Odoo. It replaces an older workflow mechanism with direct application logic, helping keep invoicing-related features consistent and maintainable without changing day-to-day business usage.

account.invoice workflow is removed and replaced by python code in addons/account, adapt in enterprise.
