fix: aircraft categorization, fullscreen satellite imagery, region dossier rate-limit, updated map legend

- Fixed 288+ miscategorized aircraft in plane_alert_db.json (gov/police/medical)
- data_fetcher.py: tracked_names enrichment now assigns blue/lime colors for gov/law/medical operators
- region_dossier.py: fixed Nominatim 429 rate-limiting with retry/backoff
- MaplibreViewer.tsx: Sentinel-2 popup replaced with fullscreen overlay + download/copy buttons
- MapLegend.tsx: updated to show all 9 tracked aircraft color categories + POTUS fleet + wildfires + infrastructure
