This is a hotfix/hack for a conflict between website_quote and
website_sale, on the field website_description.
The conflict happens when both modules are installed.
Fixes#20118
website_sale and website_quote both did their own
form_feedback. This causes issues because:
1. it would force upcoming features to have to be duplicated as well
2. there's a risk that improvements/bug fixes will only be applied to
one module, an example of this happening is
46c5f93b6c.
Until now, you could only sign and confirm a sale order from the frontend.
From now on, you can also pay sale orders if the 'Immediate Payment'
option is checked on the sale order.
