Typo in Classes/Service/TcpdfWrapper.php line 133: The code uses heigth (typo) instead of height, causing an "Undefined array key 'heigth'" warning when rendering PDFs with header logos.

  if (!empty($config['height'])) {                                                                                                                                                                              
      $view->assign('heigth', $config['heigth']); // typo: heigth instead of height                                                                                                                             
  }

Expected behavior/output
The code should use the correct spelling height to access the configuration value without warnings.

  if (!empty($config['height'])) {                                                                                                                                                                              
      $view->assign('height', $config['height']);                                                                                                                                                               
  }
