ui: switch Graph to bucket grid layouting

This change introduces bucket grid layouting, which sorts the nodes into buckets based on how they are connected. Each
bucket is then layouted individually before they are arranged next to each other. Edges go from left to right, except
for inheritance edges that go from bottom to top.
