Subject: [PATCH] FN-6115: remove workflow lane chevron icon

Remove the workflow lane chevron while preserving collapse behavior.

- remove the chevron icon import and button contents from the workflow lane toggle
- keep the existing lane toggle button and accessible label behavior intact
- add a regression test that asserts the lane toggle renders without an svg icon
