When configuring a sales channel in a SaaS shop, you get a list of all connected domains to this instance.

When using the SaaS shop as a headless store API, you won’t point your store’s domain to the Shopware SaaS backend to serve whatever frontend is in place.
Therefore it would be useful to have the option to configure any domain, and not only connected domains, in a sales channel.

And in order to create emails with correct URLs for order confirmation, sign-up etc., we need to remove the constraint that only connected domains can be used as sales channel domains.

Idea: To keep it user-friendly, you could provide auto-completions with connected domains?

Important note: You still need to enforce the use of connected domains for mailing.
