Fixed an issue that prevented Kubernetes CronJobs in non-monitored namespaces from being filtered out when namespace filtering was enabled, causing them to incorrectly appear in monitoring.

Impact: Any rules set up to monitor CronJobs in non-monitored namespaces will no longer generate alerts until the namespace is added to monitoring.

Recommended action: After updating, please review the list of namespaces monitored by the special agent to ensure all desired namespaces are included.
