feat(v0.1.4): SMART tile icon, IP locale robuste, copier HTTP, nettoyage UI

- Agent: détection IP via server_ip en priorité (fallback 8.8.8.8) — résout 0.0.0.0 sur LAN sans internet
- Agent: détection auto des disques /sys/block (sd*, nvme*) + fix continue dans la boucle smartctl
- Agent: SupplementaryGroups=disk dans le service systemd pour accès smartctl
- Dashboard: icône SMART (shield-check/triangle-exclamation) dans la ligne disque de la tuile
- Dashboard: bouton Copier compatible HTTP (fallback execCommand si clipboard API indisponible)
- Dashboard: suppression du texte redondant dans la section INSTALLATION AGENT
