Investigate and identify frontend/backend DTO mismatches

There are a number of places where the DTO's on the frontend and backend don't match. This leads to hidden/inaccessible fields existing on DTO's.

**Acceptance Criteria**
- [ ] Find all cases
- [ ] Create tickets to fix

**Time Box**
- up to half day of work

This could possibly be one: API has empty 'modified by' on the decision, but the database has a 'modifies uuid'

**Additional Context**
- DTO - Data Transfer Object - takes the data from the db and structures it in a way that is consumable to the API
