Fix: the wrong selection under the hand mode (#7541)

## Summary

Fixed an inconsistency where nodes were resizable in Hand mode. Resizing
is now restricted to Selection mode only tomatch standard LiteGraph
behavior (Hand mode should only be for panning).

## Changes

What: Disabled node resizing logic when the canvas is set to Hand mode.

## Review Focus

Try toggling between Selection and Hand modes. Verify that resize
handles are unresponsive in Hand mode but work
normally in Selection mode.
