feat: add VAD threshold controls and smooth gate ramp

Browse Source 
Replace the hard 0/1 VAD gate with a 20ms ramp in the worklet to prevent
clicks on open/close transitions. Expose positive and negative speech
probability thresholds as user-adjustable settings (defaults 0.5/0.35).
Sliders with restore-defaults button added to the VAD section of the
audio settings tab.
