Content type and archive listing move from files to file_details

Every probe rewrote its file's row on the HDD (content_type, archive):
a new row version on a random page and an entry in each of the five
indexes. They now live in file_details on the NVMe; files rows are
inserted once. files:move-details copies the existing values after
the deploy; a later migration drops the old columns.
