Web API: return visits most-recent-first and document the order
The list of visits (see example) is returned oldest-visit-first and that's generally not what a user would want, especially given that one needs to go through the entire pagination to get the most recent one. The API should return visits in most-recent-first order instead.
Also, we should document what the order is in the documentation (which is currently silent about the sort criteria).
