Support for Forward Auth

[hiasr]

Description

Currently Jellyseerr only supports password based authentication. While full OIDC support is in the works, as seen in the roadmap, it could be nice to support Forward Auth. Which would enable users to use their existing SSO with minimal effort.

Desired Behavior

When checking the authentication upon page load, check whether the request contains a certain header (i.e X-authentik-username), which should be predefined or configurable in settings. Jellyseerr can trust that the header contains the username of an authenticated user. The general flow of new user/first admin/... can follow the current flow of a new Jellyfin user.

Additional Context

I would be willing to work on this, but first want to validate whether this is a contribution you would be willing to accept!
