Introduce a new shipment packages system to allow handling shipments
consisting of multiple individual packages. This includes a new
ShipmentPackage model, a dedicated database table, and a repeater
field in the Filament ShipmentResource for managing package details
such as weight, dimensions, and declared value.
Additionally, update the AWB PDF generation service and template to
include a detailed breakdown of all associated packages when multiple
items are present.
