Select Vue Nodes After Drag (#5863)

This pull request refactors the node selection logic in the Vue nodes
event handler composable to simplify the function signature and improve
single vs. multi-selection behavior. The main change is the removal of
the `wasDragging` parameter from the `handleNodeSelect` function, with
selection logic now determined by the current selection state. Related
test code is updated to match the new function signature.

**Node selection logic improvements:**

* Refactored the `handleNodeSelect` function in
`useNodeEventHandlersIndividual` to remove the `wasDragging` parameter,
making the function signature simpler and relying on selection state to
handle single vs. multi-selection.
* Updated the selection logic to check if multiple nodes are already
selected using `isLGraphNode`, and only perform single selection if not.

**Code and test updates:**

* Updated all calls to `handleNodeSelect` in the composable to remove
the `wasDragging` argument, ensuring consistent usage throughout the
codebase.

* Updated all related test cases to use the new `handleNodeSelect`
signature without the third parameter.

**Utility import:**

* Added an import for `isLGraphNode` from `@/utils/litegraphUtil` to
support the updated selection logic.## Summary
