feat: Version 1.10.0 — DB-Zugriff auf PHP-Bridge (DB4js_all.php) umgestellt

- lib/db.ts entfernt, mysql2-Abhängigkeit gestrichen
- lib/phpdb.ts: HTTP-Client für alle DB-Operationen via DB4js_all.php
- Alle API-Routen und Server Actions auf phpdb.ts umgestellt
- compose.yml / docker-compose.prod.yml: MySQL/phpMyAdmin-Container entfernt
- app/api/DB4js_all.php/route.ts: Proxy für Statistik-AJAX-Calls
- Statistik-Grafik liest ab 2026 live aus logbuch statt StatistikJahre
- PHP 7.3-Kompatibilität: str_contains → strpos
