[BUG] Stylesheets do not load on Django administration

[Notarin]

Describe the bug

Django administration does not respect the environmental variable for taiga front end host/domain, instead it relies on the backend domain, which results in the stylesheets not loading due to being mixing http and https

How can we reproduce the behavior

by default bind any port excpet 80 and 443, setup a proxy from port 443 to configured port, and configure taiga-front accordingly ensure https is configured correctly visit django administration, page will display, but resources in the

tag link to taiga-back link, resulting in them being blocked for security
