Fix service status icon mismatch with single source of truth architecture

- Remove duplicate status string fields from ServiceData and SubServiceData
- Use only Status enum as single source of truth for service status
- Agent calculates Status enum using calculate_service_status()
- Dashboard converts Status enum to display text for UI
- Implement flexible metrics system for sub-services with label/value/unit
- Fix status icon/text mismatches (inactive services now show gray circles)
- Ensure perfect alignment between service icons and status text
