New Feature – FEA Signature API Improvements

Introduced several improvements to the FEA Signature API to simplify the signing process and allow FEA signatures to be created directly from signer information.

The update includes:

• firstname, lastname1, and lastname2 are now required fields when using sign_method: "fea".
• Added support for the rut field for FEA identity verification, using the format 11111111-1.
• contact / contactId is no longer required for FEA signatures.
• FEA signing can now be initiated directly using the signer information provided in the API request.
• Updated the POST /v1/sign/start API documentation to reflect the new FEA requirements.

These improvements simplify the integration by allowing FEA signing processes to be initiated without creating or associating an existing Legale contact.
