TT-7355 Improve racetrack UI on Tablet

[nghtctrl]

Changes:

• Removed a lot of redundant code checking for BOLD workflow
• Made the passage title, workflow step title, and step complete checkbox row rigid, so that truncation would work properly (i.e., the workflow step title will now always display in the middle)
