Create shipment for an order

Creates a new shipment manifest (Lieferschein) for an order containing one, some, or all items from the order.
If `lines` is omitted or empty, all remaining unshipped items from the order are included automatically.
On individual line items, `amount` is optional and defaults to the remaining unshipped quantity for that article.
Auto-assigns the shipment number formatted as `<order_number><shipment_prefix><index>`, e.g. `AUF-000001-L-1`.
Updates the materialized `ordersummary` table (`shipped_quantity`, `is_shipped`) and emits SSE events
(`order`, `shipment`) so that the order list and summary tables are rerendered in real time.
