fix: tolerate ~5s timestamp drift in UpdateNoteReplyText

The API returns reply timestamps that are ~1s ahead of what -collect
originally stored, so an exact TimeStamp match in the UPDATE was
hitting zero rows for every note - the API call worked, the reply
text came back, but nothing landed in the DB. Match within +-5s
instead. Also return rowsAffected from UpdateNoteReplyText and
report it separately from notes-seen in the summary so misses are
visible.
