Porta la funzionalità QR code dalla versione Vue a Flutter.
Condividi: pulsante in fondo alla tab Pasti (attivo solo con piano
non vuoto) → bottom sheet con QR code generato da qr_flutter.
Payload: { "v": 1, "meals": { ... } }, limite 2953 byte.
Ricevi: pulsante sempre visibile → QrScanPage full-screen con
fotocamera via mobile_scanner, cornice di mira, validazione
struttura JSON e importazione via MealPlannerProvider.importPlan().
Nuovi package: qr_flutter ^4.1.0, mobile_scanner ^5.0.0
