Formats impression configurables + recadrage au ratio

Config admin :
- Chaque format (10x15, 13x18, 15x20) activable avec checkbox
- Imprimante CUPS assignable par format

Écran impression :
- Boutons de format (seuls les activés apparaissent)
- Cadre de recadrage au ratio du format (3:2, 18:13, 4:3)
- Auto-détection portrait/paysage
- Cadre déplaçable avec poignées tactiles
- Galerie → Valider → écran impression avec print_list
