Restructure SAM rough mask workflow for sidebar preview

- Add roughMaskThumbnailScale state with $watch to sync with main scale slider
- Update sidebar thumbnail to use transform:scale() for consistent zoom between views
- Modify openRoughMaskInNewWindow() to create HTML page with matching scale
- Add denoise strength slider (10-100%) visible only when rough mask exists
- Backend already supports denoise_strength parameter in prepare_mask_workflow_with_start()
- Rough mask auto-clears after successful extraction
- Add Playwright tests for UI changes and API parameter acceptance
