Initial commit: Dispensa - home pantry management app

Features:
- Barcode scanning (QuaggaJS) + Open Food Facts API lookup
- Inventory management with locations (Frigo, Freezer, Dispensa)
- Product database with Italian product suggestions
- Expiry date estimation by category
- AI expiry date reading via Gemini Vision API
- Flexible unit of measure (pz, conf, g, kg, ml, L)
- Nutriscore/NOVA/Ecoscore/allergens display
- Mobile-first PWA with offline support
- SQLite backend with PHP REST API
