Ajout de tests unitaires et mise à jour du rapport de couverture

Ajout de tests unitaires pour les fonctions de gestion des processus et des protocoles de transport.
Mise à jour de la configuration de couverture pour générer un rapport JSON au lieu de HTML.
Les tests couvrent les formats de chaînes OS, les propriétés des structures ProcessPortInfo et TransportProtocol, ainsi que les comportements de base de la fonction find_process_using_port.
