feat: lista spesa con tab Da comprare/In previsione, tag, frequenza, tap-to-scan

Browse Source 
- Counter nei tab aggiornati dinamicamente
- Auto-aggiunta prodotti CRITICI a Bring! al caricamento (1x per sessione)
- Badge urgenza e frequenza sugli item in lista (cross-ref smart shopping)
- Tag locali per item (Urgente/Priorità/Verificare) con menu dropdown
- Ordinamento automatico per frequenza utilizzo (item più usati in cima)
- Tap su un item → scanner barcode, con banner 'Trovato! Rimuovi dalla lista'
- Fix pctLeft: usa max(1, qty) come fallback refQty per evitare falsi alert
- Fix daysLeft capped a 365gg per pulire stringhe di previsione
- Back button on action page → torna a shopping se aperto da lista
