feat: generate unique chain ID and genesis for new nodes

- Generate unique chain ID based on hostname (ait-{hostname})
- Add genesis block generation step to deployment script
- Each new node gets its own chain/island instead of sharing ait-mainnet
- Update environment files with node-specific configuration
