fix(netmap): résolution DNS via Livebox pour les noms d'appareils

nmap forcé sur 192.168.1.1 avec -R --dns-servers pour récupérer
les hostnames DHCP enregistrés par la Livebox (.home).
Ajout du champ netbios (script nbstat) et affichage du meilleur
nom détecté (NetBIOS > hostname DNS) avec badge de source.
