Audio input settings (device picker, VAD/PTT mode, VAD sensitivity, mic gain, PTT key) move from the always-visible bottom panel into Settings > Audio..., matching the macOS/iOS pattern. The device ComboBox now uses DataSource + DisplayMember="Name" instead of Items.Add() with no DisplayMember — this fixes both the display bug (was showing the full DeviceInfo record ToString()) and the NVDA silence on dropdown open (DataSource binding exposes proper MSAA text per item). Changes apply live for immediate feedback; Cancel reverts. VoiceSettings gains InputDeviceId to persist the chosen device across sessions. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
