Janis Eccarius	ab95b4f101	fix(spark): replace shared spark-events PVC with emptyDir to fix Multi-Attach error ... local-path provisioner is RWO-only; attaching a single PVC to master, two workers, history-server, and streaming pod on separate nodes causes Multi-Attach errors. Each pod now gets its own ephemeral emptyDir for /spark-events. Event logging confs removed from CronJobs and streaming Deployment (logs are pod-local and do not persist across restarts).
