Remove Balsamiq File Preview

See merge request gitlab-org/gitlab!82924

The Balsamiq File Preview is not utilized a lot. In fact it has been
broken since over a year on gitlab.com and on self managed instances[0].
The Balsamiq preview itself doesn't have a lot of value as it just
renders the preview of the first Balsamiq page and not all the pages.
We have received no user complaints whatsoever, meaning that likely
_noone_ relied on this feature.

This MR removes the previewer, as it is also riddled with tech debt, for
example shipping a asm.js compiled version of sql.js

Changelog: removed

Add "Created on" & "Last activity" columns to groups and projects page
