feat: Telegram OSINT map layer, Osiris intel ports, and maritime settings

Add Telegram OSINT with hourly incremental t.me scraping, metro geocoding
separate from news centroids, threat-intercept popup UI with inline media,
and HTML markers above alert boxes so pins stay clickable. Expose GFW_API_TOKEN
in onboarding and Settings Maritime; harden GFW/CCTV/geo fetchers. Port Osiris-
derived recon, SCM, entity graph, malware/cyber feeds, sanctions, and submarine
cable layers with tests and documentation.
