    Composing a provider's network policy onto a sandbox is gated behind this

    The setting is gateway-global. Exclusivity against other xdist workers is
    provided by the ``exclusive_gateway_config`` marker plus the autouse
    ``_gateway_config_guard`` guard (see conftest): no concurrent worker is
    mid-test while this fixture mutates and restores the setting, so none can
    observe the transient value. Depending on the guard here also orders the
    exclusive lock acquisition before the mutation.

    ``GetGatewayConfig`` returns known keys even when unset, with an empty
    ``SettingValue`` (no populated oneof), so the setting is treated as present
    only when its value oneof is set; otherwise restore is a delete. ``global``
