Chore: simplify wording for person entities

- Replaced all instances of "Unnamed Member" with "Someone Unnamed"
- Removed unused UNNAMED_MEMBER constant
- Renamed UNNAMED_PERSON to THAT_UNNAMED_PERSON to match its value
- Renamed UNNAMED_USER to UNNAMED_PERSON and changed the value to "unnamed person"
