Name the Local area, say what each News section needs, and credit its sources

Local reads the area at the view centre (`/outline?at=`) and asks the feed
for its reports (`at`): the area is outlined faintly on the globe and named
at the top of the section ("News from Kazakhstan"; within 500 km at sea).
A disputed area is named as itself. A read that a newer look replaced, or
one left behind by a switch to Conflicts, is dropped, and a server without
the area route is asked once.

A section read from a key the server lacks says which key it needs
(503 `no_key`), that the key was refused (`key_rejected`) or that its
daily allowance is spent (`key_quota`); the other section keeps reading.
Liveuamap and World News API join the key registry.

Cards name the service a report came through ("via GDELT Project"), and
Liveuamap and Natural Earth are credited once their data shows. Economy is
a category of its own. Disputed-area labels are smaller and show the name
only; outlines keep up to 300 parts.
