test: fix LGraphNode tests by mocking TransformState and useNodeResize

- Add TransformState injection mock for tests
- Mock useNodeResize composable since tests don't need resize functionality
- Fixes test failures after making TransformState required for resize
- Rename .spec.ts to .test.ts to follow tests-ui conventions
