fix(server): relayStatus checks actual tunnel worker process state

The relay tunnel runs as a separate Workerman worker that creates its own
RelayConsumer directly. The container's RelayConsumer was a different instance
that was never started. This caused admin UI to always show 'Disconnected'.

Now relayStatus checks:
1. If phlix-relay-tunnel process is running (via pgrep)
2. Recent log entries for 'tunnel active' status

Also added helper methods isTunnelWorkerRunning() and getTunnelLogState().
