✨(backend) add Traefik reverse proxy support for media-auth

Adds support for serving media behind Traefik, which currently cannot work
at all.

The media-auth subrequest views read the original request URL from a
hardcoded HTTP_X_ORIGINAL_URL header. That header is an nginx-ingress
convention. Traefik's ForwardAuth middleware sends X-Forwarded-Uri instead
and has no mechanism to emit X-Original-URL, so behind Traefik every
recording download and file attachment is rejected with a bare 403 --
indistinguishable from a legitimate permission denial, which makes it
painful to diagnose.

Add MEDIA_AUTH_ORIGINAL_URL_HEADER, defaulting to HTTP_X_ORIGINAL_URL so
existing nginx-ingress deployments are unaffected. Traefik deployments set
it to HTTP_X_FORWARDED_URI. It is used in both places that resolve the
header: RecordingViewSet._auth_get_original_url and the file attachment
_authorize_subrequest. The log message on a missing header now names the
header actually expected, which is what makes the failure diagnosable.

This mirrors the setting the sibling Docs project already exposes
(suitenumerique/docs, MEDIA_AUTH_ORIGINAL_URL_HEADER) for the same reason.
