fix(news): keep World News API's own category for a country's news

The bundled rules read fighting and crises; in everyday headlines their
words mislead ("Kazakhstan Advances in Global Digital Rankings" read as
ground fighting). A country's own stories in Local now keep World News
API's category (politics, business, else other) and carry no severity.
Fighting in the area still shows through the Conflicts reports placed
there.
