feat(issue): add batch issuance support for multiple credentials

Refactors `issueDocumentByConfigurationIdentifierAttested` to accept a `List<String>` of credential configuration identifiers, enabling simultaneous issuance of multiple documents (mdoc and sd-jwt) in a single request.

The single credential variant is deprecated and delegates to the new batch version.
