[IMP] web: revert warnings display in back-end

Fix for: https://github.com/odoo/odoo/pull/32132

We had changed the display of the warnings in the back-end to be like the
front-end (notification toast). This change needs to be reverted. Now
the warnings in the front-end are toast notifications and in the
back-end they are Warning modals.
