Extract the Playback/Capture and Voice Activation tabs (device pickers,
gain/volume sliders, noise reduction, VAD/PTT tuning, microphone test)
into DevicesPanel and VoiceActivationPanel, alongside the existing
NotificationsPanel/HotkeysPanel/IconPackPanel/ClientVersionPanel. A new
FormPanel base holds the shared GridBagLayout scaffolding. SettingsDialog
is now a thin coordinator (753 -> 187 lines); its public API and all
settings read/write behavior are unchanged.
