HPCC-8805 Fix query selection problem on BrowseQueries page

Recently, I added a View Query Details link on BrowseQueries page
and removed the query selection by misunderstanding. Without the
query selection, the buttons of Activate, Delete, and Toggle
Suspend will not work on that page. This fix adds the query
selection back. The View Query Details link is replaced by a new
button of 'Query Details'.
