Import USB + éditeur complet + widgets

- Service USB watcher (polling montages, scan photos récursif)
- Écran accueil avec détection USB live (bouton vert + compteur)
- Éditeur : crop interactif avec overlay/grille des tiers
- Éditeur : filtres Pillow (N&B, sépia, vintage, contraste)
- Éditeur : stickers/goodies draggable + cadres overlay
- Éditeur : multi-pose (5 templates, remplissage auto)
- Éditeur : texte éditable draggable
- Éditeur : rotation, annulation, export scène PNG
- Widget CropOverlay avec poignées tactiles
- Widget GoodiesPanel (stickers + cadres depuis assets/)
- Widget MultiposeDialog (prévisualisation templates)
