feat: limit config_to_agent to core configuration keys

- Remove support for advanced Agent parameters in config_to_agent
- Only support: model, prompt, tools, name in configuration
- Advanced parameters can still be passed via kwargs
- Remove agent_id test and update function mapping
- Keep interface simple and focused on basic agent configuration
