Sale Readonly Security

This module introduces a single extra permission, "Sale orders edition", found in the Usability section of the user rights. Only users who have this permission can create, modify or delete sale orders; the administrator gets it by default.

For everyone else, sale orders open in a read-only way:

• The action buttons at the top of the sale order form (the header area) are hidden.
• Create, edit and delete actions are blocked, and Odoo shows the message "Sorry, you are not allowed to create/edit sale orders. Please contact your administrator for further information."
• Creating an invoice from a sale order is also blocked, because the module checks the same permission before generating the invoice.

Reading sale orders is still allowed, so users can consult them without changing anything. The module only touches the sale order model (sale.order) and does not add menus, reports or scheduled actions. It works together with the standard Sales app and its access rights.
