…ire_login to v9

Example of module which requires such refactoring:

https://github.com/it-projects-llc/website-addons/tree/10.0/website_sale_checkout_store

[FIX] condition to show normal checkout button was wrong in website_sale_suggest_create_account
I was equal to

(user_authenticated or not signup_allowed and can_checkout)

while it has to be

(user_authenticated or not signup_allowed) and can_checkout

This test was expecting sign up to be disabled because `auth_signup` is not in its module graph, but since that addon is autoinstallable, it could be installed without our knowledge.

Just make sure signup is disabled before running the public user test, to make it unitary.

Also, moved to at-install mode, since the post-install one adds no value.

Updated by "Update PO files to match POT (msgmerge)" hook in Weblate.
