Fix multi-bootstrap RQLite cluster setup

- Primary bootstrap (57.129.81.31): starts new cluster (no join address)
- Secondary bootstrap (38.242.250.186): joins primary bootstrap cluster
- Regular nodes: join primary bootstrap cluster

This allows both VPS servers to be bootstrap nodes while forming a
proper RQLite cluster where the secondary bootstrap joins the primary
instead of trying to start its own independent cluster.

Should resolve the leadership establishment timeout on the second VPS.
