feat: badges SMART pills, versionning serveur, fix copier HTTP

- Dashboard: icônes SMART → pills OK/USAGÉ/PREFAIL/HS cliquables
  (tuile + popup détail + popup SMART redessiné pour novices)
- Serveur: constante version 0.1.0 exposée via WS server_stats → footer
- Fix copier script install en HTTP (isSecureContext avant clipboard API)
- install.sh: ajout ethtool, suppression logique OVERWRITE_CONFIG
