Describe the bug

Upgraded from 2025.10.0 to 2025.12.0.

Now my custom brand logo is gone and not displayed. Reports 404 Not Found.

Authentik puts this URL into the DOM:

/files/media/public//media/public/flow-backgrounds/logo-wide.png?token=eyJhbGciO.....

This HTTP endpoint seems not to hit the Authentik proxy container. My Traefik reverse proxy responds with 404.

How to reproduce

1. Upgrade to 2025.12.0
2. Custom brand logo not displayed

Expected behavior

Brand logo should be displayed
