fix: correct debian changelog format (add missing 0.3.5 header)

- Add ServiceStatus struct with name, display_name, active_state, sub_state,
  load_state, enabled_state, main_pid, healthy fields
- Add get_service_status() to PackageManagerBackend trait
- Implement get_service_status() in AptBackend with systemd and OpenRC support
- Add get_service_status HTTP handler in system.rs
- Add /system/services/{name} route
- Add E2E test for service status endpoint
- Bump version to 0.3.6
