Update a fiscal profile

Rotate the CSD (upload the new files raw via multipart — curl -F csd_cer=@new.cer -F csd_key=@new.key -F csd_password=...; base64 JSON also works), replace the FIEL, set the PDF brand color/logo, edit legal_name/zip, or update metadata. A rotated CSD must belong to the same RFC.
