List notes on a contact
The private notes this account has written about one person, newest first. Notes live inside SuperX and are never posted anywhere. Not paginated: notes are per-contact and few.
Works for any X id the account already has a note on, whether or not that person is still one of its contacts; an id with no notes returns an empty array, not a 404. Only creating a note requires a known contact.
