feat: implement role-based configuration system for CLI with automatic API key management

- Add role detection to command groups (admin, client, miner, blockchain)
- Load role-specific config files (~/.aitbc/{role}-config.yaml)
- Add role field to Config class with environment variable support
- Implement automatic role detection from invoked subcommand
- Add development mode API key bypass for testing (APP_ENV=dev)
- Update CLI checklist with role-based configuration documentation
- Add configuration override priority and
