feat: add AUTOBAHN option to local docker cluster (CON-247)

- NodeKey.SaveAs writes node_pubkey.txt alongside node_key.json
- FilePVKey.Save writes validator_pubkey.txt alongside priv_validator_key.json
- step1 copies pubkey files to shared volume for cross-node access
- step4 generates autobahn JSON config from all nodes' pubkeys when AUTOBAHN=true
- Wired through docker-compose.yml and Makefile

Usage: AUTOBAHN=true make docker-cluster-start
