Adds configurable Voice Activity Detection (VAD) settings for Assist voice input, persists them in preferences, surfaces them in the Assist settings UI, and forwards them to the Assist websocket pipeline request.

Changes:

• Add Assist VAD preference storage (get/set) and plumb settings through config manager and view models.
• Extend runAssistPipelineForVoice websocket API/payload to include vad_silence_seconds and vad_timeout_seconds.
• Add settings UI fields (Compose) + strings and expand unit/screenshot tests.
