Subject: search: translate d: to dt: in query

dt: is higher resolution and the YYYYMMDD column will be dropped
if there's ever another SCHEMA_VERSION update.  While the
upcoming code repo index is independent of the mail schemas,
it'll use similar query prefixes and likely use d:/dt: for
Author Date of git commits.
