Add system indicators back to data page

Since `formatted_value` got removed from the API indicators response, system-level indicators weren't displaying on the data page.  This adds back the (unformatted) data value for system indicators, instead of displaying "No Data Available."  Also puts into translation files some untranslated strings.
Cool - I think as a property this should work too; it was returning formatted values when I tested before and this used to work so maybe something else changed that broke this.

The intention was to not store translated strings in the database since which translations are going to be used depends on the request.
