Sebastian Krüger 38a2b2962d feat: add export scope options (project/selection/tracks) ...

Implemented Phase 11.3 - Export Regions:
- Added export scope selector in ExportDialog
  - Entire Project: Mix all tracks into single file
  - Selected Region: Export only the selected region (disabled if no selection)
  - Individual Tracks: Export each track as separate file
- Updated ExportSettings interface with scope property
- Refactored handleExport to support all three export modes:
  - Project mode: Mix all tracks (existing behavior)
  - Selection mode: Extract selection from all tracks and mix
  - Tracks mode: Loop through tracks and export separately with sanitized filenames
- Added hasSelection prop to ExportDialog to enable/disable selection option
- Created helper function convertAndDownload to reduce code duplication
- Selection mode uses extractBufferSegment for precise region extraction
- Track names are sanitized for filenames (remove special characters)
