fix: use persistent storage for Docker data-root instead of ephemeral /mnt (#37)

The Azure ephemeral disk (/mnt) gets wiped on VM deallocate, causing
Docker images to be lost and pool-resume to fail with WAA timeout.
Move Docker data-root to /home/azureuser/docker (OS disk, persistent)
and increase OS disk to 128GB to accommodate Docker images.
