Clear the mirror from the blocklist before the provisioning sync, not after it

A previous offboard blocklists the mirror and rsync.sh refuses blocklisted hosts, so on a re-onboard Step 1e was being refused and the auth stack would have deployed against empty directories.

+#
+# The blocklist was cleared inside Step 8, which was fine while every rsync in the onboard came
+# after it. Step 1e does not: it runs before the containers are deployed, which is the whole
+# point of it. On a re-onboard that ordering means the provisioning sync is refused, the auth
+# stack comes up against empty directories, and the step built to prevent exactly that reports
+# a failure nobody can explain from its own output.
+#
+# Un-blocking here is not a loosening. The offboard's own summary says "re-onboard to permit
+# access again" — an onboard is the event that permits it, and this is where the onboard starts
+# needing it. Step 8 still runs its own clear; removing an absent entry is a no-op.
