The adapter was forwarding the downstream client's client_id and
redirect_uri to Authelia, which would always be rejected — Authelia
only recognises client_id=keycape and its registered callback URI.
Also removed downstream PKCE forwarding: KeyCape is a confidential
OIDC client to Authelia and authenticates via client_secret instead.
