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.

 - **Panel.** The right-rail NEWS panel (`src/ui/newsPanel.js`, `src/ui/news/`) has a time window at the top (the server's 24 h, or 12, 6, 3 or 1 h; the hotspot counts are read for the chosen window) and two sections. **Conflicts**: hotspot chips with counts, a severity floor (significant and above by default), a category filter, the chosen event, and a continuous feed, newest first. **Local**, while the camera is below 3,000 km: every report in the area at the view centre, named at the top ("News from …") and outlined on the globe, which then shows those reports instead of the hotspots' news; at sea, reports within 500 km. A disputed area of the bundled list (11, see `src/data/local_data/natural_earth/README.md`), or a territory Natural Earth gives no country code (Somaliland, Northern Cyprus and others), is named as itself and read from no country's outlets; elsewhere Natural Earth's default country lines apply. Each card shows the publisher's picture when the event has one (hotlinked, no referrer, publisher credited), the headline (a model's English headline marked as such), a mono meta line (severity marker, category, place, sources, age), who reported it, attestation and media chips, and the service it came through ("via GDELT Project"). Open, a card plays the post's clip on request. A click flies the camera straight down from 150 km and selects the report.
 - **Notices.** A section whose key the server lacks says "{provider} key required" and names the variable; a refused key says "{provider} refused its key"; a spent daily allowance says "{provider} limit reached for today". The other section keeps working.
 - **Source.** `sources.news` (`createNewsSource`, export `./layers/news/source`) reads same-origin `/api/news/*` with a 15 s timeout, a 4 MiB cap and record-by-record validation; `newsQueryAllowed` lets a host admit exactly the client's requests. Core's local server (`server/providers/news.js`) forwards only those GET requests to `GEV_NEWS_ORIGIN` when it is set.
-- **Built-in backend.** With `GEV_NEWS_ORIGIN` unset, Core answers the same routes itself (`server/providers/news/keyed.js`). **Conflicts** needs no key: the last 24 h of GDELT 2.0 event exports (15-minute files on `data.gdeltproject.org`, about 100 KB each), physical violence only (CAMEO roots 18–20), one report per story with copies of one agency story merged, placed at GDELT's location for it (a town the article's words name beats a bare country). Titles are the article's page title from GDELT's GKG export of the same quarter hour (about 6 MB each) for the newest 3 h, else the words of the article's address; GDELT's actor coding is never shown. With `LIVEUAMAP_API_KEY`, Liveuamap's mapped items stand beside GDELT's. **Local** reads World News API (`WORLDNEWSAPI_KEY`) by the source country at the view centre, once per country every 30 minutes (about 1.5 points a read, at most `WORLDNEWSAPI_DAILY_READS` reads a day, default 30), plus the Conflicts reports placed inside the area. Areas come from the bundled Natural Earth countries and disputed areas (`server/providers/news/areas.js`). Categories, relevance and severity are bundled rules (`categorize.js`); a news server may replace them.
