Closes KAFKA-18584 ### Summary - Exercise `testControllerRestart` under both isolated and combined KRaft modes. - Keep the shared Raft manager alive while the broker still owns it during a combined-mode controller restart. In combined mode, `ControllerServer.shutdown()` previously shut down the shared Raft manager even though the broker continued using it. Restarting the controller could then observe a null manager and fail with the NPE reported in KAFKA-18584. The lifecycle guard preserves the manager until the broker releases it. ### Tests - `./gradlew :test-common:test-common-runtime:test --tests org.apache.kafka.common.test.junit.ClusterTestExtensionsTest --no-build-cache --console=plain` - `./gradlew :core:spotlessCheck :test-common:test-common-runtime:spotlessCheck --no-build-cache --console=plain` - `./gradlew :core:checkstyleMain :test-common:test-common-runtime:checkstyleTest --no-build-cache --console=plain` The targeted regression test passed three fresh reruns for both KRaft modes, and the full `ClusterTestExtensionsTest` passed. -- This is an automated message from the Apache Git Service.
