Initialisation des variables potentiellement non définies (PHPStan lvl 1)

[kwizer15]

Description

Ajout de l'initialisation des variables qui peuvent être utilisées avant d'être définies, détectées par PHPStan au niveau 1.

Chaque modification est une simple initialisation de variable ($var = null, $var = [], etc.) avant un bloc conditionnel ou une boucle qui l'assigne. Aucun changement de comportement.

Fichiers concernés :

• core/ajax/eqLogic.ajax.php — $eqLogic
• core/ajax/scenario.ajax.php — $converts
• core/ajax/user.ajax.php — $configs (appel config::byKeys manquant)
• core/api/jeeApi.php — $object, $cmd, $scenario, $update (x2)
• core/class/history.class.php — $goupingType
• core/class/interactQuery.class.php — $closest, $objects, $cmd
• core/class/jeeObject.class.php — $events
• core/class/update.class.php — $url
• core/class/utils.class.php — $return
• core/class/widgets.class.php — $_needRefreshWidget
• core/php/utils.inc.php — $return dans pageTitle()
