### What changes were proposed in this pull request? This PR aims to enable `spark.shuffle.service.enabled` by default in `SparkCluster` resources. The default is applied before the user-provided `sparkConf` and `confOverrides`, so any user-specified value takes precedence. ### Why are the changes needed? In Standalone mode, dynamic allocation requires the external shuffle service, which must be enabled at Worker launch time. Defaulting it to `true` makes every `SparkCluster` dynamic-allocation ready out of the box, while users can still opt out by setting `spark.shuffle.service.enabled=false` in `spec.sparkConf`. ### Does this PR introduce _any_ user-facing change? Yes. `SparkCluster` Workers now start the external shuffle service by default. Setting `spark.shuffle.service.enabled=false` in `spec.sparkConf` restores the previous behavior. ### How was this patch tested? Pass the CIs with two new test cases in `SparkClusterSubmissionWorkerTest` covering the default and the user-override case. ### Was this patch authored or co-authored using generative AI tooling?
