refactor: move From/To with blockies into Identity block

Move From and To address fields (which include blockie identicons)
from the Value block into the Identity block, per review feedback.
From/To are identity information, not value information. The Value
block now contains only Amount, Native quantity, and Token contract.

README TransactionDetail section updated to match.
