fix: resolve silent voice playback on VPS and queue screenshare streams

- Call unpause() when starting a stream in DiscordPlayer to prevent getting stuck in a paused state.
- Call stop() instead of pause() in VoiceController on disconnect to fully reset the player.
- Add user-agent header to ffmpeg calls in MusicPlayer and Transcoder to prevent YouTube 403 Forbidden on VPS.
- Add screenshare streams to the media queue when successfully started.
