Sync PHP backend feature parity: IP detection, database backends, API endpoints, and frontend

- IP detection: Cloudflare IPv6, ULA IPv6, proxy header chain, offline GeoIP DB - Database: add SQLite (pure Go, no CGo) and MSSQL backends - API: add JSON result sharing endpoint and ID obfuscation - Frontend: add modern CSS design, design switcher, favicon - Compatibility: ?cors parameter support, human-friendly distance rounding - Update Go to 1.21, add modernc.org/sqlite and maxminddb deps
