feat: show running pod count after workflow deploy

[Cynthia-0203]

What this PR does / Why we need it:

Show the running pod count in workflow container service deploy logs after the deployment succeeds.

What is changed and how it works?

After CheckDeployStatus returns StatusPassed in the deploy job wait phase, the deploy job now:

• Collects the pod owner UIDs from the deployed resources.
• Lists pods by the related pod labels collected during deployment.
• Filters pods by owner UID to avoid counting pods from old ReplicaSets or unrelated workloads.
• Deduplicates pods by pod UID.

Does this PR introduce a user-facing change?

• API change
• database schema change
• upgrade assistant change
• change in non-functional attributes such as efficiency or availability
• fix of a previous issue
