Envío de pedidos del TPV al SII

This module connects Point of Sale orders with the Spanish SII (Suministro Inmediato de Información) tax reporting. Once a POS session is validated, its orders are automatically queued and sent to the SII.

On each POS order you get a new "SII" tab showing the description, refund type, registration key, send date and the SII result (state, errors, CSV and technical response). A "Send to SII" button lets authorised users send an order manually, and a "Send now to SII" link can force an immediate submission.

Business rules shown in the code: - Only paid or done orders are eligible, and only when the company has SII enabled, the order is a simplified invoice and it has not already been invoiced afterwards. - Orders already sent to the SII cannot be invoiced again; an error is raised if you try. - Negative orders are treated as corrective (refund type "I", invoice type "R5"). - A scheduled job runs every 5 minutes to send pending orders.

In the POS orders list you can filter by SII not sent, pending modifications, sent, failed, cancelled, and group by SII error. A company setting "SII POS Description" defines the default description used on POS orders.
