TASK 22: global audio sync offset (positive delay at the mixer out)
Adds AudioSyncOffsetMs (0..500ms, default 0) that delays the whole
interleaved-stereo mix so audio lands on the video when it runs ahead —
OBS's documented lip-sync fix. Positive-only: advancing audio needs a
video-side delay and is out of the audio layer's scope.
- Services/Audio/AudioSyncDelay.cs: pure delay line, flushed on Configure
- AudioMixer: Func<int> syncOffsetMs seam + delay applied post-limiter
- LayoutStore.Settings + MainViewModel.Audio/VM: load/save + binding
- PreviewPane mic bar: SYNC slider + status dot (IntToSyncBrushConverter)
- AudioSyncDelayTests: identity, negative/beyond-500 clamps, 10ms→960 samples
Reference (external scan): https://obs-versions.com/blog/how-to-fix-audio-delay-on-obs
(audio ahead => positive delay). Verified: build 0 warnings; 3/3 delay tests pass.

refactor: split Audio out of MainViewModel — Commit 6/12
MainViewModel.Audio.cs: mic bar (AudioLevel/MeterFillWidth/MeterBrush,
MicVolume/MicMuted, ToggleMicMute, PickMicrophone), mic status dot
(MicStatus/MicStatusBrush/MicStatusToolTip), game bar
(GameAudioLevel/GameMeterFillWidth/GameMeterBrush, GameAudioVolume,
GameMuted, ToggleGameMute), PushSystemVolume, mixer event handlers
(OnMicLevelChanged/OnLoopbackLevelChanged/OnMicConnected/OnMicFailed),
StartMicCaptureAsync, command properties, 18 fields.
Kept in core: TraxIdleBrush, TRAX code block, ctor wiring
(mixer init + event hookup), timer construction.
Verify: 0 warnings, 246 passed, 2 known failures only.
