refactor(audio-tab): I.3 — split AudioTab.tsx 521 → 97 LOC across 6 files (#674)

* refactor(audio-tab): extract useAudioDevicesProbe hook Pull the device-list state, refreshAudioDevices callback, mount probe, and the audio:device-changed / audio:device-reset listener wiring into hooks/useAudioDevicesProbe.ts. macOS short-circuit lives in the hook. AudioTab.tsx: 521 → 463 LOC. * refactor(audio-tab): extract AudioOutputDeviceSection Pull the audio output device picker (macOS notice + CustomSelect + refresh button) into components/settings/audio/AudioOutputDeviceSection.tsx. AudioTab.tsx: 463 → 418 LOC. * refactor(audio-tab): extract NormalizationBlock Pull the engine picker (Off / ReplayGain / LUFS) and the engine-specific config blocks (RG mode + pre-gain + fallback; LUFS target + pre-analysis attenuation with reset) into components/settings/audio/NormalizationBlock.tsx. AudioTab.tsx: 418 → 267 LOC. * refactor(audio-tab): extract PlaybackBehaviorBlock Pull Crossfade ↔ Gapless mutually-exclusive toggles + Preserve Play Next Order into components/settings/audio/PlaybackBehaviorBlock.tsx. The crossfade-seconds slider only renders while crossfade is the active mode. AudioTab.tsx: 267 → 201 LOC. * refactor(audio-tab): extract TrackPreviewsSection Pull the track previews subsection (master toggle, per-location grid, start-ratio slider, duration slider) into components/settings/audio/TrackPreviewsSection.tsx. AudioTab.tsx: 201 → 97 LOC.
