Drop the Traefik-level basic auth layer — keep only Hermes's own login

By request: one auth layer, not two. Note this isn't really removing a
layer I added on top of nothing — Hermes's own gate is mandatory and
can't be disabled while the dashboard is reachable through a separate
Traefik container (it fails closed at startup on any non-loopback bind
without a configured auth provider). The only thing actually optional
was the Traefik-level middleware, so that's what comes out; Traefik now
just does TLS termination + routing.
