Bind-mount state to /media/disk1/containers/volcanic_secretary

Switch from named volumes to bind mounts under one host directory so
the workspace, pi-agent, and claude state is easy to back up / inspect
on the Coolify host.

Also re-adds the sleep-infinity override so the container stays up
while claude auth is redone against the new (empty) claude bind mount.
