feat(storage): make one samba ss for kantai3 node

Since a samba server uses a host port, there can only be one per node.
This patch reworks storage to have a single samba server on kantai3 (nee
kaidame), and adds the homeassistant-backup share to it, in addition to
the existing and initial media1 share.
