[fix] Enable AUDIO_RECORD widget in both LiteGraph and Vue nodes modes (#6094)

Fixed the AUDIO_RECORD widget to display correctly in both rendering
modes:

- Removed conflicting AUDIO_RECORD registration from ComfyWidgets that
was blocking the custom widget implementation in uploadAudio.ts
extension
- Changed canvasOnly flags from true to false on both audioUIWidget and
recordWidget to enable Vue nodes rendering
- Added type override (recordWidget.type = 'audiorecord') after widget
creation to enable Vue component lookup while preserving LiteGraph
button rendering
- Removed unused IAudioRecordWidget type definition

The widget now works correctly:
- LiteGraph mode: Displays as a functional button
- Vue nodes mode: Displays full recording UI with waveform visualization
