overall looks good, but, as discussed, let's use the full input media source instead of just one track

Looks good, but I realized we need to clear the connected MediaStream when a peer connection is closed, or it will be kept in memory in the global state even when not in use.

This makes me think that dispatching from the attachInputAudioToPeerConnection is the wrong place, since we would like to keep the dispatch and clean up logic in the same place.

I think the canonical react solution would be to put this in the useEffect in useRtcConnection, since the clean up logic could then be put inside the return value of that useEffect.

More specifically, in use-rtc-connection.ts:

1. dispatch the connected audio stream inside the if (inputAudioStream !== "no-device") { check on line 172
2. dispatch an event that sets the connected media stream to null inside the return value on line 188
