List anchor changes GET

Each change contains a complete snapshot of the record at that point in time, the action performed (`create`, `update`, or `drop`), and a timestamp. Changes are returned newest first. After a record is deleted, its change history remains accessible but must be queried using the record's LUID instead of its handle.

Signer
