Brainstormed design for a new 'objednávky vydané' document type — purchase
orders you author with line items and export to PDF, alongside the existing
customer orders (which become the 'přijaté' tab).
Key decisions: dedicated issued_orders/issued_order_items models mirroring
invoices; customers reused as supplier/partner; NET+VAT-on-top; dedicated
numbering sequence; reuse of orders.* permissions; standalone v1 (no
warehouse/received-invoice links).
