The ssh-config endpoint was using RequireAuth which only accepts Pulse
API tokens, but the setup script sends a temporary setup token via the
auth_token parameter. Updated to follow the same pattern as
verify-temperature-ssh: check setup token first, then fall back to API auth.
This fixes the 401 error when the setup script tries to configure ProxyJump
for containerized Pulse deployments.
