fix: ServiceStatusData deserialization mismatch with agent response

Manager expected fields: name, status, healthy, uptime_secs
Agent actually returns: name, display_name, active_state, sub_state,
load_state, enabled_state, main_pid, healthy

Updated ServiceStatusData to match agent response format.
Updated health_check_poller.rs to use new field names.
