일반 데이터 클래스 수정 및 잠재적인 데이터베이스 마이그레이션

데이터 클래스에 필드를 추가합니다.

This Kotlin file below defines a data class. I need to add a new field.

Please prompt me for the name of the new field.

Then with that information, update the data class, its constructor, and any
functions in this file that use it to handle the new field, including proper
null checks if applicable.  If database access is present, generate a migration
function within this file to add the field to the corresponding table.
