CP-12545 docuseal conversion bugfixes (#60)

* add audience as prefill to template creation

* this is primarily for conversion from ATS to Docuseal, since these fields would normally just be updated through the Docuseal iframe itself

* update manager first and last name label

* use word map to properly display Firstname as First Name, Lastname as Last Name

* add warning log if invalid audience is passed in

* fix line length
