Guillermo Pages 09d06bc085 fix: add persistent connections + fix self::$pdo bug ...

- Add PDO::ATTR_PERSISTENT to prevent SQL Server connection storms
  under concurrent PHP-FPM load (was causing 241 SQLSTATE[08001]
  failures/day on callioapi)
- Fix bug: $pdo → self::$pdo in connect() and getPDOInstance()
  guards (was checking undefined local var instead of static prop)
