fix: couleurs icônes, boutons carrés, sidebar collapsée, langue, SW scope, LXC arrêté

Icônes :
- Sidebar navItems : couleur distincte par section (iconStyle via data-binding)
- Sidebar footer user : couleur primary
- Navbar : logout → danger, soleil → amber, lune → blue
- Panel widgets : œil visible → success, caché → muted

Boutons :
- `.neu-btn--sm:has(> i:only-child)` → carré 2rem×2rem automatiquement
  (theme, logout, mode édition) sans modifier le HTML

Sidebar :
- --sidebar-width-collapsed : 64px → 52px
- Sidebar réduite : icônes centrées (justify-content center)

Langue :
- Setter vide sur `lang` dans navbar() pour corriger x-model avec getter
  (le @change gère la vraie mise à jour du store)

Service Worker :
- Enregistrement depuis /ws.sw.js (scope /) au lieu de /js/ws.sw.js (scope /js/)
- build.mjs : copie ws.sw.js vers dist/ root en plus de dist/js/

LXC arrêté :
- checkTarget() : skip si target.status !== 'running' → évite les 502 SSH
