feat: enhance East Asia coverage with adversary bases, news sources, ICAO ranges, and PLAN vessel DB

- Add 68 military bases (PLA, Russia, DPRK, ROC, Philippines, Australia)
  with data-driven color coding (red/blue/green) on the map
- Add 6 news RSS feeds (Yonhap, Nikkei Asia, Taipei Times, Asia Times,
  Defense News, Japan Times) and 15 geocoding keywords for islands,
  straits, and disputed areas
- Extend ICAO country ranges for Russia, Australia, Philippines,
  Singapore, DPRK and add Russian aircraft classification (fighters,
  bombers, cargo, recon)
- Create PLAN/CCG vessel enrichment module (90+ ships) following
  yacht_alert pattern for automatic MMSI-based identification
- Update frontend types and popup styling for adversary/allied/ROC
  color distinction
