Motivation
For a DorisDisaggregatedCluster, FE replicas must not be smaller than electionNumber. Today an invalid update such as reducing FE replicas from 2 to 1 while electionNumber is 2 can be accepted first and only corrected later during reconciliation. That delayed correction can still patch the FE StatefulSet and trigger unnecessary FE restart behavior.
