fix: get reports api performance tuning

[goemen]

Description

The custom raw query returned lots of data that needed to be transformed and formatted to the required API response shape. This approach was causing performance issues. This fix uses SQL views to create a union of the pay_transparency_report and report_history and another view that creates a union of the calculated_data and calculated_data_history.

Prisma has a functionality to include SQL views in the schema, allowing us to join the two views making the queries faster.
