feat: let operators create test orders from approved quotes

Without an approved card payment there was no way to try the board, the
files and the print flow in production. "Criar pedido de teste" on an
approved quote creates the order through the same path as a paid one, marked
TESTE on its card and panel and audited; neither it nor its stage moves
queue anything for Tiny or WhatsApp.
