Part of #118592 (closed)

At the moment the users statistics is calculated on page load and each value is calculated separately. With this merge request the statistics will be rendered by using the data stored in the users_statistics database table which will be updated daily via a worker.

The users statistics was only available for paid instances before but will now also be available for Core users.
