[fix] Prevent drag activation during Vue node resize (#7064)

## Summary
- Add isResizingVueNodes flag to layoutStore
- Set flag in useNodeResize during resize operation
- Check flag in useNodePointerInteractions to skip drag activation

Fixes a bug where resizing a Vue node after selecting it would
incorrectly trigger drag logic, causing the node to teleport.
