- incs/db.php: db_verbinden() setzt utf8mb4, strikten sql_mode und schaltet die mysqli-Exceptions von PHP 8.1+ ab, damit die bestehenden "or error(mysqli_error())"-Pruefungen weiter greifen. - db_abfrage/db_zeilen/db_zeile/db_wert mit ?-Platzhaltern (mysqli_execute_query, PHP 8.2). - Alle neun kopierten mysqli_connect/select_db-Stellen nutzen jetzt db_verbinden(). Nur zusammen mit der auf utf8mb4 migrierten Datenbank einsetzbar. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
