Curated static catalogue of 13 conflict theatres (Ukraine, Gaza, Sudan,
Myanmar, DRC, Yemen, Syria, Lebanon, Sahel, Somalia, Red Sea, Taiwan
Strait, Korean DMZ) with war|high|elevated severity and short factual
descriptions. GET /api/conflicts returns { zones: [{id,label,severity,
lat,lon,description,eventCount,lastUpdated}], timestamp } where
eventCount rolls up pre-existing geocoded news/GDELT//api/news/map rows
inside each zone bbox (0 when the tables are empty). Adds the conflicts
entry to overlay_catalog(). No upstream scraping, no jittered coords.
