Update Mesa-LLM Examples for the New SolaraViz API

Mesa-LLM does not modify or add new Mesa visualization components. However, changes to the SolaraViz API may require the existing example models to be updated to remain compatible with the latest Mesa version.

## Proposed Changes
- Update Mesa-LLM example models to use the latest SolaraViz API.
- Replace outdated SolaraViz API usage with the current implementation.
- Update visualization-related code in the affected examples.
- Verify that the updated examples run correctly with the latest Mesa version.

Locate the Mesa-LLM example models and their current SolaraViz usage, then compare those calls with the latest Mesa SolaraViz API. Update the affected visualization code and run the examples with the latest Mesa version to verify they still work.
