[Checkout] Remove redirection to homepage when checking out in shops that 'display only shopfront'

[audez]

What is the need / problem?

The UX when clicking the "Checkout" button on shops that display only shopfronts is not very friendly.

The fact of being kicked out of the shopfront page and redirected to the homepage is tough, and the error message "The hub you have selected is temporarily closed for orders. Please try again later.” doesn't help much.

Which type of users does this problem affect (and how many, if known)?

- Shoppers

Potential solutions that will solve the problem ?[[brainstorming to list feature candidates]

Stay on shopfront instead of redirecting to homepage, and change error message to “ This is a display only shop, you won't be able to order. Please contact the shop owner for more info.”

The ideal thing would be to create a proper "Display only shopfront" feature, as it has been discussed here or here
But in the meantime, this solution could help improving the experience.

Additional context

“Display only shopfront” option is described in the user guide. It can be achieved by setting all payment methods to "backoffice only".
