Mark unfrozen Supply archive posts and open them in the Supply run

The Supply archive presented every post as a frozen, read-only list, even a
past week's Supply run that week_rollover had not frozen and that the
Supply run route could still change. Each archive post now carries frozen;
a post not yet frozen is marked (Current, or Still open for a past week)
and links to the Supply run, where it can still change. Only frozen posts
open read-only in the archive.
