karmor probe doesn't limit scope of a policy to a namespace

Bug Report

karmor probe cli incorrectly links policies to workload in different namespaces.

I am applying a policy to my cluster. To check that I got the labels correct and that the policy was applied to my workload, I ran the "karmor probe" command. I saw in the report that the policy was applied. After looking a little closer, I saw that I actually applied the policy to the default namespace, not the namespace where my workload was. "karmor probe" still linked them

General Information

• Environment description GKE and Kind
• Kernel version
• Orchestration system version in use (e.g. kubectl version, ...) $ kubectl version Client Version: v1.31.1 Kustomize Version: v5.4.2 Server Version: v1.30.3-gke.196900
• Link to relevant artifacts (policies, deployments scripts, ...)
• Target containers/pods

To Reproduce

1. Create Namespace
2. Start workload in namespace. (kubectl exec -n validator -i -t postgres-0 -- bash)
3. Apply wrong policy

4. Run karmor probe.

In the included screen shot, you can see that there is only 1 policy on the system and that it is in the default namespace, yet the policy is listed under a workload in the validator namespace.

Expected behavior

In this example, the policy shouldn't be listed at all. There aren't any workloads that should apply.
