App 2.42.0: music-sources check on the Logs tab

Before a now-playing display, find where the head unit tells what is
playing, read only: the players Android reports, the active media
sessions, and every media browser service with its song, CarPlay's
(com.allgo.remoteui.mediabrowserservice) among them. The report is saved
and sent like a signal recording (shared SignalRecorder.saveCopies).
Also the findings of the first two recordings from the server.
