feat(dashboard): distinguish parent and child relations on a graph

[VladyslavG]

I had a task to refactor some fixtures in the Codux. I decided to use our feature graph for that and it was really useful.
However when viewing feature graph I noticed that all links - parent and child are highlighted in the same color. I could not understand looking at a graph where was my feature requested as a child. Take a look at this:

I hovered over file-assets and it is impossible to tell which related feature uses file-assets vs which is used by file-assets.

So I propose to use different colors for parent links vs child links. I used this approach personally in my abovementioned task and it helped me a lot! So I decided to create this PR, maybe it will help other people when playing with features

After applying my changes:

You can clearly see different colored lines and distinguish parent vs child relations.
If you don't like the suggested color, please feel free to fix it.

have you tried to run yarn engine analyze ?
I think we should invest more there...maybe even move this graph to it.
my plan is to remove the original dashboard package in the feature.

@VladyslavG what was the motivation here? do you need better analysis?

yarn engine analyze

my motivation was to understand relationships between features visually without reading the code for each feature. And that graph (with my tweak) was very helpful.
yarn engine analyze doesn't help me to visualize feature dependencies
