Improve the layout of the Workflow Visualizer (#8372)

- Increase the dimensions of the ReactFlow nodes. This allows to ditch
scaling which made it hard to get the width of the nodes as they were
visually scaled by 1.3.
- Center the flow when the flow mounts and when the state of the right
drawer opens.
- Put the node type inside of the node so it doesn't overlap with the
arrow
- Make the edges non deletable

We'll have to make a refactor so the viewport can be animated properly:
