docs(pm): the census paragraph names its own denominators and dates the freeze move

Two precision fixes inside the re-taken census, both measured: the population
line now separates files SCANNED (1,014) from files carrying such a line (441),
and the 65 sites that moved `refused` -> `unread` are attributed to the round
that made freeze transparent rather than to this one, which changes no verdict
at all.
