[DASHBOARDS] Move all the graph computing logic to the backend (#17189)

- Create resolvers for each type of charts which needs data
transformation after the group by operation: Bar Chart, Line Chart and
Pie Chart
- Move all the utils to the backend and refactored some into services

This allows all the computation to be done in the backend, improving
performances in the frontend.
