Add request body parameter 'Attribute Type', 'Attribute Description', '1009 Box Number', '1099 Percent', 'Paid from' in POST Invoice endpoint for FE NXT.

To Set values of 'Attribute Type', 'Attribute Description', '1009 Box Number', '1099 Percent', 'Paid from' fields using SKY API for Invoice there is no JSON request parameter. So add these parameters.
