This update makes Odoo easier to use for people who rely on screen readers by improving labels, image descriptions, icon descriptions, dialog behavior, and menu structure. It helps more users navigate accounting, reporting, delivery, and configuration areas independently and reliably.

Today, Odoo is really tricky to use without seeing the screen, it must be improved to be usable.

This PR forbid to use labels without a "for" attribute, add some title, rule and aria attributes in HTML. With that, Odoo will be fully usable with a screen reader.
