fix(marker): tolerate port conflict on marker listener startup
When the configured marker_listen_port (default 3070) is already in
use, fall back to an OS-assigned port instead of crashing the server.
If even port 0 fails, log the error and continue without marker
signals — traffic insight degrades rather than taking down startup.
