feat(health): add health status for ExternalSecret, Job, HPA, and Namespace (#662)

Add condition-based health status calculation for additional resource kinds:
- ExternalSecret: checks "Ready" condition
- Job: checks "Complete" and "Failed" conditions
- HorizontalPodAutoscaler: checks "AbleToScale" and "ScalingActive" conditions
- Namespace: handles "Terminating" phase as Progressing

Closes #418
