Wheel Selection Toolbox and Popover (#5781)

This pull request updates event handling in the selection toolbox
components to ensure that mouse wheel events are properly forwarded to
the canvas, improving interaction consistency across the UI.

**Event handling improvements:**

* Changed the wheel event handler in `SelectionToolbox.vue` to use
`canvasInteractions.forwardEventToCanvas` instead of
`canvasInteractions.handleWheel`, ensuring wheel events are consistently
forwarded to the canvas.
* Added the wheel event handler to the `MoreOptions.vue` popover,
forwarding wheel events to the canvas for submenu interactions.

**Code organization updates:**

* Imported `useCanvasInteractions` in `MoreOptions.vue` to access the
new event forwarding method.
* Instantiated `canvasInteractions` in `MoreOptions.vue` for use in
event handling.## Summary
