[NOV] Updates on the Cielo E-commerce API documentation

Guidance on authentication verification in 3DS in credit and debit transactions:
- To confirm if authentication was applied during authorization, check the ECI value in Payment.Eci;
- The API replicates the ECI provided by the merchant in Payment.ExternalAuthentication, but the actual value used by the card brand is the one in Payment.Eci.
Information about the SentOrderId field in credit and debit transactions:
- When MerchantOrderId does not comply with the acquirer’s rules, a new order number is generated and returned in SentOrderId.
- If the format is valid, SentOrderId returns the same value provided in MerchantOrderId.
Rule for the Visa Retry Program:
- Code 14 is now considered in Category 1 and also in Category 3 (Data Quality).
Error code 100 in void operations:
- Occurs when a partial void attempt is made before the transaction is settled.
