fix(news): list Local newest first

Local ranked its reports by severity first. A country's own news now
carries no severity, so in a conflict area GDELT's reports (severity 1
and up) could crowd every one of its stories out of the 40 listed.
Local is now newest first; severity still shows by colour.

Also: readTitle reads Conflicts headlines only, the economy category's
comment and the attribution popover name World News API's category,
and KNOWN-ISSUES names Core's ids for World News API's categories.
