Reverse sorting of "My Apps"

### Problem description

New apps currently appear on the bottom of the app lists on https://tabrisjs.com. It is usual for newer apps to be more actively developed, so they need to be accessed more often. The user has to scroll to the bottom of the app list to see them.

### Expected behavior

To improve UX, the app list should be sorted chronologically in increasing order based on their creation date, with the most recently created apps being shown on the top of the list.
