feat: include Job and CronJob pods in service pod lookup

[vigneshrajsb]

Summary

• extend the service pod resolver to include Job and CronJob workloads
• include completed and failed Job/CronJob pods while preserving Deployment and StatefulSet terminal filtering
• add unit coverage for Deployment, StatefulSet, Job, Job selector fallback, CronJob child Jobs, and empty workload results

Root cause

The service-level pods endpoint only resolved Deployment and StatefulSet selectors, so service workloads represented by Jobs or CronJobs returned an empty pod list even when those pods existed at the build namespace level.
