ArctosDB/arctos#7318

Summary

• Create an Agent Attribute model
• Implement it for Code Table Request - agent attribute - verification status arctos#7328
• (Preview of next Issue: Make sure everything works, then proceed to Phase Two, moving all agent metadata to the Attributes model established with this Issue)

User Interface Changes

Likely a preview of a new structure for a new concept in the current Agent edit UI.

Possibly a preview of an all-new Agent page (eg if old and new libraries are incompatible).

Data Structure Changes

New structure previews a merge/simplification.
