Adjust Plus Button Placement for Conditional Steps

We're improving the placement of the plus (+) button for Conditional steps to make workflow building smoother.

Since Conditional steps don’t typically require tools, the top plus button is currently positioned too far from the step. We’re adjusting it to sit closer to the top edge of the diamond shape, ensuring a more intuitive and efficient workflow experience.

Additionally, we’re adding a blue highlight to the plus buttons (like other step types) around Conditional steps for better visibility.
