This pull request improves the handling of cancelled orders across the display and manager interfaces, ensuring that cancelled orders are properly removed from all relevant lists and that users are notified with a localized warning message. It also adds new translation strings for the cancellation notification in both English and Italian.

Order cancellation event handling:

• Added an event listener for the order-cancelled event in app/display/page.tsx to remove cancelled orders from both readyOrders and prepOrders state lists.
• Added an event listener for the order-cancelled event in app/manager/page.tsx to remove cancelled orders from confirmedOrders, readyOrders, and pickedUpOrders, and to display a warning toast notification to the manager.
• Imported the toast notification library in app/manager/page.tsx to support user notifications.

Localization:

• Added the orderCancelled translation string to the English locale in lib/i18n/locales/en.ts.
• Added the orderCancelled translation string to the Italian locale in lib/i18n/locales/it.ts.
