feat(upload) : anneau focus clavier, activation Entrée/Espace et prop clearable

- Anneau de focus clavier sur le champ (via useKbdFocusRing)
- Ouverture du sélecteur de fichier au clavier (Entrée / Espace)
- Nouveau prop `clearable` (défaut false) : croix `mdi:close` focusable
  (Entrée/Espace, anneau clavier) qui vide le champ et émet l'event `clear`
- Playground : carte de démonstration "Clearable"
