feat: Introduce Balloon Lasso Tool for mesh extraction

- Added BalloonTool workspace tool to facilitate the extraction of balloon meshes in the 3D viewport.
- Implemented ActivateBalloonTool operator to activate the Balloon Lasso Tool.
- Refactored BalloonLasso operator into ExtractBalloon for better clarity and functionality.
- Enhanced properties for balloon extraction, including mode, thickness, resolution, and material reuse options.
- Updated SnapFormSettings to include new balloon-related properties.
- Improved material and image handling for balloon extraction, ensuring compatibility and reusability.
- Added tests to validate the registration and functionality of the new balloon tools and properties.
