InfoSys — Rapport système HTML

Génère un fichier HTML autonome avec toutes les informations système du serveur :
CPU, mémoire, stockage, réseau, matériel PCI, services actifs, paquets installés, top processus.
Ce que contient le rapport :
Vue d'ensemble (hostname, OS, kernel, uptime, load)
CPU (modèle, cœurs, fréquence, cache)
Mémoire RAM + swap
Stockage (arborescence lsblk + utilisation df)
Réseau (interfaces, IP, MAC, routes)
Matériel PCI / DMI (si disponible)
Services systemd actifs
Paquets installés (dpkg)
Top 20 processus (CPU + mémoire)
Le fichier est sauvegardé dans /tmp/ avec le nom infosys__.html et le chemin est affiché à la fin.
