[web] Expose metric for active users in SP (#20130)

* [web] Expose metric for active users in SP

* Removed redundant UserHandler.setupLoginData()

In the past this method was also calling
a now deleted notifyDomainLicence(), but now
this is just an alias for populateTeamInvites()

* Added migration for `lastActive`

* Added secondary read precedence to count active users
