feat: enhance item routing modal configuration

- Added new properties for configuring the item addition modal's maximum width and list height in the ItemRoutingConfig interface.
- Updated the ColumnEditor component to include additional content for modal size settings, allowing users to specify width and height in pixels.
- Adjusted the ItemRoutingComponent to apply the new configuration settings for the modal's dimensions, improving the user experience by providing more control over modal appearance.

These changes aim to enhance the flexibility and usability of the item routing modal within the application.
