   UI-1.5 — coquille finale : vrai rail vertical desktop + tiroir mobile.

   Principes :
   - #mainNav reste le même point de montage du router (aucune route ni
     permission modifiée), mais vit désormais dans <aside .app-sidebar>.
   - Desktop/tablette large : rail vertical sticky, couleur principale.
   - <= 760px : tiroir global piloté par #appNavToggle, distinct du tiroir
     Administration existant (#adminMobileToggle).
