Creates a new SEPA file by collecting all approved payment orders and generating
a SEPA-compliant XML file.

SEPA File Generation Process

When a SEPA file is created, the system:

1. Collects all payment orders with "approved" status
2. Generates a SEPA-compliant XML file
3. Updates payment orders to link them to the SEPA file
4. Changes payment orders status to "paid"

Requirements

• At least one payment order with "approved" status must exist
• The customer must have banking details configured (IBAN)

Output

The API returns the created SEPA file object with a URL to download the generated XML file.
