As a sysadmin, I want to see **all** insights in the chosen time interval in the observatory, not only 6
Currently we display only a max of 6 insights in the observatory, even if there are more. As there are not constrains on space, I believe we could display all insights in the chosen interval, without any need to paging.
For the case of insights that are repeated, we should group them as described by the issues #263 and #231
