[REF] *: use 'frontend' system in non-website apps

* account, auth_signup, payment, portal, project, sale, sale_management,
  web_unsplash, website, website_mail, website_rating, website_sale

This commit does probably not do what is stated for all non-website apps
but it is a first step. It also uses the system in apps which could have
already used it but did not.
