v1.10.2 patches: continent persistence, city markers, dynamic map center

C changes:
- gstorage.c: encode continent into root key for --persist --restore survival
- gholder.c: decode continent from root + lat/lng storage
- commons.h: add lat/lng fields to GMetrics struct
- geoip2.c/geoip1.h: extract coordinates from MMDB
- json.c: output lat/lng in geolocation JSON

JS changes:
- Remove cityIndex guard for static HTML city dots
- TopoJSON lat/lng fallback for city coordinates
- updateMap fallback city collection
- Dynamic orthographic center based on visitor count
- Mercator stays at [0,15] for full world view
