Bug: new tab click idioms don't work on workspace, workspaces, and templates page page

When I `<middle>`-click, `<ctrl>`-click, or `<cmd>`-click on one of these rows, I should get the destination page in a new tab

Currently `<middle>`-click does nothing and `<ctrl>`-click acts as a normal click.  I haven't tested `<cmd>`-click, but I assume it's the same.
