Activity visualization

In order to see how much the sms is used, we think about adding visualizations as they are there in gitlab for the activities:

We can do that similar to gitlab per user (only visible for the user itself), per main entity (device, platform, site, configuration) and globally.

This way we analyse the usage in the sms even more.

However, all what we do here needs to be complied with the data privacy statement. (We don't want to blame users).
