fix(preset): wrap LOCAL_INTERNET_RADIO stream URL in Orion location

The speaker's BMX module calls GET on the stored preset location and
expects a BmxPlaybackResponse JSON from the AfterTouch Orion endpoint.
Storing a bare stream URL (e.g. http://davefmradio.no-ip.org:8000/stream)
causes BMX to receive raw ICY audio, which it cannot parse; playback
silently stays on the previous source and no error is surfaced.

Add --service-url / SOUNDTOUCH_SERVICE_URL to `preset set`. When set
alongside --source LOCAL_INTERNET_RADIO and a raw HTTP(S) location, the
CLI wraps the stream URL in the Orion station endpoint:

  <service-url>/core02/svc-bmx-adapter-orion/prod/orion/station
    ?data=<base64({"name":"…","imageUrl":"…","streamUrl":"…"})>

Without --service-url the command still works but prints a clear warning
explaining why the saved preset is likely to not play, rather than saving
a silently broken location.
