CodePress CMS v1.9.0: visitor statistics with SVG world map and GeoIP

- Add GeoIP class with provider chain: local DB-IP Lite, MaxMind .mmdb, external API
- Add built-in pure-PHP MMDBReader so .mmdb works without Composer
- Add cli/geoip-update.php to download DB-IP Lite and build a compact binary index
- Add cli/generate-world-map.php to generate the world map SVG from Natural Earth TopoJSON
- Add Analytics class aggregating stats in admin/storage/stats.json with LOCK_EX
- Add admin statistics page with choropleth world map, country list, top pages,
  daily chart, referrers and a period filter
- Add GeoIP and privacy settings with database update and stats reset buttons
- Add optional IP anonymization and configurable retention period
- Add country field to requests.log (parser accepts 7, 8 or 9 fields)
- Add country column to request log and KPI cards to the dashboard
- Ignore GeoIP binaries and stats.json in Git
- Update TODO.md, guides and version to 1.9.0
