Add function to retrieve agent names from configuration

- Introduced `get_agent_names_from_config` function to map agent IDs to their entity names from the simulation configuration, enhancing clarity in action representation.
- Updated simulation scripts to utilize this new function for fetching agent names, ensuring that real entity names are displayed instead of default identifiers.
- Improved handling of agent names by falling back to default names only if not specified in the configuration, maintaining consistency across simulations.
