Refactor Cutout Tool to Use World Space Edge Length

- Replaced the Mesh Detail parameter with a new Edge Length property to define cutout sampling in physical units.
- Introduced Minimum Relative Edge Length preference to control effective spacing based on the bounding box of the cutout content.
- Updated tests to validate the new edge length functionality and ensure consistent behavior across different resolutions and canvas sizes.
- Removed deprecated parameters and adjusted related properties to align with the new edge length implementation.
- Enhanced geometry sampling logic to utilize effective world spacing for both standard and fine outline modes.
