fix(voice): remove OggDemuxer from transmitter pipeline

Browse Source 
Opus.Encoder in prism-media outputs raw Opus packets directly,
no OGG wrapping. OggDemuxer was breaking the stream by
trying to unwrap a non-existent OGG container.

Pipeline was: PCM → Encoder → OggDemuxer → Discord (broken)
Pipeline now:  PCM → Encoder → Discord (correct)
