refactor: migrate blockchain CLI commands to use centralized config and update port assignments

- Replace load_multichain_config() with ctx.obj['config'] in all blockchain commands
- Update blockchain RPC port from 8003 to 8006 throughout CLI
- Add blockchain_rpc_url and wallet_url fields to Config class with environment variable support
- Update node status command to use new port logic (8006 for primary, 8026 for dev)
- Update installation docs to reflect new blockchain RPC port (8006)
- Update

cli/aitbc_cli/commands/blockchain.py
