entrypoint: chown devbox-ssh-local volume so jump key generates
The named-volume persistence change for ~/.ssh-local did not update the
entrypoint's volume-ownership loop. Docker creates named volumes as
root:root, so setup-lan-access.sh (running as developer) silently failed
to mkdir/ssh-keygen, leaving no jump key and breaking LAN access on the
first --force-recreate. Add ~/.ssh-local to the chown list.
