feat: improve reporting performance

Here is my review of the PR:

Description

This PR updates the campaign reporting view with a new analytics dashboard. It allows toggling different metrics, viewing data breakdowns by day, hour, ad set, ad, and OS, and filtering the date range and OS. The old reporting view is still accessible via a "Revert" button.
