feat(dashboard): resize souris, DnD live, panel widgets, icônes corrigées

- Resize widget via drag sur le coin bas-droit (mousedown → mousemove →
  snap à taille 1 ou 2 colonnes selon distance)
- DnD live : les autres widgets se déplacent pendant le drag (onDragEnter
  réordonne le tableau + onDragEnd restaure si annulé)
- Mode édition : panel latéral avec tous les widgets (œil toggle visible/masqué),
  survol d'une entrée met en avant (outline) le widget correspondant dans la grille
- Bouton mode édition : icône seule (lnid-pencil-1)
- Correction noms d'icônes LineIcons (lnid-pencil-1, lnid-eye, lnid-eye-closed,
  lnid-cross → supprimé en faveur de toggles dans le panel)
- Suppression des classes CSS obsolètes (edit-mode-banner, widget-add-btn, etc.)
