fix(test): restore the ecash network before bouncing the service

The restore proof's cleanup set the network back *after* restarting
archipelago, so the call landed on a socket that wasn't listening yet
and failed silently. A fully green run left the node parked on testnet —
the one outcome a cleanup path must never produce, and worse for being
invisible.

Network first, while the RPC is still up; then the wallet file, then the
restart, then wait for the service back so a check running straight
afterwards doesn't meet a dead socket.
