Fix service metrics not showing - remove cache check

Browse Source 
The service_status_cache from discovery only has active_state with
all detailed metrics set to None. During collection, get_service_status()
was returning cached data instead of fetching fresh systemctl show data.

Now always fetch fresh data to populate memory_bytes, restart_count,
and uptime_seconds properly.
