### Which Issue(s) This PR Fixes - Fixes #10849 ### Brief Description Static-topic epoch comparators in `TopicQueueMappingUtils` and `ClientMetadata` subtracted two `long` values and narrowed the result to `int`. Epoch deltas larger than `Integer.MAX_VALUE` could therefore reverse the intended newest-first order. This change uses `Long.compare` in both ordering paths. It adds regression coverage for replacement mode selecting the latest broker mapping across the full positive `long` range and for client endpoint construction retaining the latest broker. ### How Did You Test This Change? - Confirmed the new server-side regression test failed before the fix: expected `latest` but received `stale`. - Ran `mvn -pl remoting -am -DskipITs -Dtest=TopicQueueMappingUtilsTest,ClientMetadataTest -Dsurefire.failIfNoSpecifiedTests=false test`. - Result: 15 tests passed; Checkstyle reported 0 violations; SpotBugs reported no errors or warnings. -- This is an automated message from the Apache Git Service.
