Refactor delivery and order handling: unique IDs, status methods, new fields, naming fixes, and menu/controller corrections

- Add static m_uid to DeliveryAssignment for unique IDs
    - Implement DeliveryAssignment getStatus() and setStatus()
    - Add DeliveryPartner::getAssignedDeliveries()
    - Rename pickOrderFromOrders() param to userOrders
    - Fix spelling issues and setw() widths
    - Mark non-mutating controller methods as const
    - Add newline before Net Cost output
    - Restrict cancellation to orders in CREATED state
    - Add customerUsername to Order with getters/setters
    - Implement Restaurant::addOrder()
    - Fix RestaurantOwnerMenu option 5
