- Move voice status into settings store (voiceSttReady, voiceTtsReady),
checked once at login and refreshed after admin model reload
- ChatView, BriefingView, DashboardChatInput now use computed refs from
the store — mic buttons appear reactively without needing a page reload
- BriefingView: separate STT-only guard for mic PTT vs TTS-only guard for
listen mode / speak buttons
- Add ▶ Preview button to Voice & Speed section in Settings for single-
voice testing without enabling blend mode
