Issued orders are purchase orders WE send - they must pick from suppliers
(sklad_suppliers), not from customers. Per user decision customer_id was
REPLACED (not kept alongside): migration drops issued_orders.customer_id and
adds supplier_id FK -> sklad_suppliers (existing rows lose their counterparty
- the feature is days old; re-point them in the UI).
- service: input/filters/search (suppliers.name + ico)/enrichment/detail all
supplier-based; create validates the supplier inside the transaction and
update before write -> Czech 400 'Dodavatel nenalezen' instead of P2003 500;
detail returns a minimal supplier field set (no internal notes leak)
- routes: supplier_id on list + stats; new GET /issued-orders/suppliers
lookup (orders.view/create/edit guard - orders users lack warehouse.manage
which guards the warehouse suppliers CRUD), active suppliers only,
name+id ordering
- PDF: Dodavatel block now renders the supplier (name, newline-split address,
IC/DIC), layout and both language label sets unchanged
- frontend: new SupplierPicker kit component (CustomerPicker untouched),
IssuedOrderDetail/IssuedOrders switched to supplier_id/supplier_name; the
picker keeps a fallback option for orders whose supplier was later
deactivated; WarehouseSuppliers CRUD now also invalidates issued-orders so
the picker can't go stale
- tests: issued-orders suite switched to supplier fixtures + new coverage
(lookup shape + 403, nonexistent supplier 400, PDF supplier block)
