Drop the legacy `X` suffix from `GetMasterX` and `GetReplicaX`. The presence of the suffix suggests there's a `non-X` version: but in fact we migrated these away a long time ago, so remove the cognitive overhead. As an aside, this additionally helps avoid trip up LLMs that interpret this as "something to fix".
