Automation Branching UX updates

[deanhannigan]

Description

Some additional UX updates to the new Automation branching work.

Addresses

• Added autoscrolling when dragging and dropping a step. Now when you drag a step to the extreme edge of the automation canvas, the automation will now scroll in that direction.
• UI updates - added the same colouring and background pattern as the new role management UI. Both screens have a very similar UX this makes sure they share the same visual style.
