FN-6038: swap workflow toolbar edit and create buttons

Swap the workflow toolbar actions so editing appears before creation.

- move the workflow editor pencil button ahead of the new workflow plus button in the board toolbar
- add assertions covering the full toolbar order when both actions are present
- add coverage for cases where only one workflow toolbar action is available
