Remove Odoo Branding from Website

This module changes how the website footer looks to visitors. It removes the promotional message that Odoo normally adds to website pages, including the "Create a free website with Odoo" / "Powered by Odoo" branding link.

• It works by replacing the standard footer promotional message with an empty one, so nothing is displayed in that spot.
• The change is applied through a website template that inherits the standard branding message, meaning it affects all website pages that use the standard footer layout.
• The template is marked as customizable, so it can be shown or hidden from the website editor's customization options.
• A small installation step automatically disables this template when Odoo is running in test mode, so automated tests are not affected.

No new menus, buttons, reports, or business rules are added. The module does not create or modify any database models; it only touches the website presentation layer. It depends on the Website app and is installed from the Apps list. Once installed, the Odoo branding disappears from the footer without further configuration.
