Implements SatelliteReplicationStrategy read/write/paxos plans with quorum-of-quorums semantics, built on a new CompositeTracker (replacing PerDcResponseTracker) that requires N of M child quorums to succeed. Adds SatelliteFailoverState, tracking per-range NORMAL / TRANSITION_ACK / TRANSITION state so replica layout and consistency requirements can vary by failover phase. Paxos runs within the primary DC but includes satellite/secondary summary nodes on prepare and commit via SatellitePaxosParticipants; PaxosCommitRemoteMutationVerbHandler rejects remote paxos commit mutations during TRANSITION_ACK so stale commits can't leak into the other DCs during failover.
