favor Received: date over Date: header globally

The first Received: header is believable since it typically
hits the user's mail server and can be treated as relatively
trustworthy.  We still show the Date: in per-message (permalink)
views, which may expose users for having incorrect Date:
headers, but all the ISO YYYY-MM-DD dates we display will
match what we see.
