feat: replace site registration with database-driven site addressing

Central now resolves site Akka remoting addresses from the Sites DB table (NodeAAddress/NodeBAddress) instead of relying on runtime RegisterSite messages. Eliminates the race condition where sites starting before central had their registration dead-lettered. Addresses are cached in CentralCommunicationActor with 60s periodic refresh and on-demand refresh when sites are added/edited/deleted via UI or CLI.
