feat(platform): self voice roster mute, prefs explore baseline (v0.8.103)

Phase 138 platform changes:
- Apply local voiceMedia mute/deafen to self roster row via myVoiceChannelId
  (no protomux roundtrip required for sidebar indicators).
- Persist discoveryExploreBaseline through updateUserPrefs on Explore open.
- Ingest discoveryExploreBaseline from USER_PREFS on boot and prefs events.
