Issue with assets and url_prefix

Bug report

Thanks for filling all the following fields, if they apply, and to describe your issue the most precisely you can.

Weboob's version I am using is: 3.1

Kresus's version I am using is: 0.17 with latest image from docker

Steps to reproduce: Run Kresus in a subdirectory and using url_prefix and/or KRESUS_URL_PREFIX ("/kresus")

What I expect: Assets linked with the correct path

What I observe: All resources under /assets/ directory (mostly the web fonts) are not linked according to the url_prefix

Client logs (if apply): All fonts ends up with a 404 as the browser is trying to download them from the root directory and not /kresus/assets/<...>

A quick overview of the web console:

I tried with only url_prefix set in the .ini file, then by setting only KRESUS_URL_PREFIX in the env, and also with both settings.
