Mirrors the publisher-injection pattern from FleetStatusBroadcaster and PeerOpcUaProbeActor: Props accepts an optional Action<object> override so tests can use a TestProbe sink instead of bootstrapping DistributedPubSub (unreliable single-node in TestKit). Un-skips the two RedundancyStateActor tests deferred under F6.
