Add progress bars on Vue Nodes (#5469)

* track execution progress in vue nodes

* add test

* remove pointless execution state test

The test was mocking everything including the provide/inject mechanism,
so it wasn't testing real behavior. The execution progress feature
works correctly as verified through manual testing.

* [refactor] address PR review feedback from @DrJKL

- Replace hardcoded #0B8CE9 color with blue-100 class for consistency
- Replace magic number 56px with top-14 class for progress bar positioning
- Use storeToRefs() for better Pinia reactivity
- Reduce heavy commenting per maintainer preference

* fix: update LGraphNode test to mock useNodeExecutionState properly

The test was failing because it passed executing as a prop, but the component
uses the useNodeExecutionState composable. Added proper mock for the composable
to test the animate-pulse class application during execution.
