ELE-435 Identify between artifact types at the edr report (models, sources, exposure)

Describe the problem
At the UI we cant identify between the artifact types under the models at the json which makes the frontend imply breakable logics for filtering artifacts types

Describe the solution

1. Add artifact type to the normalized model schema - selected
2. Split the models key at the json to models, sources and exposures
