feat(issued-orders): editable PDF heading 'Text objednavky (na PDF)' (order_text)

New nullable issued_orders.order_text column (migration applied to dev+test). The heading above the PDF items table is now editable per order, mirroring invoices' billing_text: empty falls back to the default, which is now 'Objednavame si u Vas:' per user wording. Field sits above Dodaci podminky in the detail form; persisted via create + update strFields (both schemas - the invoices Update-schema gap is not repeated). Tests: persistence round-trip incl. null-clears, PDF custom heading + default fallback.
