chore: simplify assignment export logic

Simplify assignment export logic so we dont need to add every value individually to the export. Makes it easier to expand the logic in the future so that if new fields are added to the assignment config, it can be added easily.

Switch logic to take everything from the assignment config and just omit fields we define.
