place.stream.media.finalizeLivestream

Turn a finished livestream into a VOD. The server concatenates the MUXL segments it recorded for the livestream(s) into a single content blob, derives the playback sidecars, and publishes the place.stream.media.track records. By default it leaves a draft VOD the streamer publishes later via place.stream.vod.publishDraft; with publish set it publishes the place.stream.video record as soon as the VOD is finalized. The caller must be the streamer, or a moderator they have granted livestream.manage; every record is written with the streamer's session.
