fix(satellite): SSE path only updates orbit position, not observer data

Browse Source 
Adds a 'source' param to handleLivePositions. The SSE path ('sse') only
applies lat/lon/altitude/groundTrack since the server-side tracker has
no per-client location. The HTTP poll path ('poll') owns all observer-
relative data and the visible-count badge.
