### Changed
- Better snapping when resize elements
<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit
- **New Features**
- Improved resizing behavior with enhanced alignment and snapping during element resizing, supporting rotation and multiple element selection.
- Alignment lines now display more accurately when resizing elements.
- **Refactor**
- Resizing logic updated to use scale factors instead of position deltas, enabling smoother and more precise resize operations.
- Resize event data now includes richer details about handle positions, scaling, and original bounds.
- Coordinate transformations and scaling now account for rotation and aspect ratio locking more robustly.
- Cursor updates are disabled during active resize or rotate interactions for a smoother user experience.
- **Tests**
- Updated resizing tests to use square shapes, ensuring consistent verification of aspect ratio maintenance.
