Refactor output directory structure and scenario runs

Updated output directory paths to remove redundant 'Outputs' subfolder, ensuring results are written directly under the base output directory. Improved InfrastructureConstants to handle output folder creation and naming more robustly. Refactored Program.cs to support multiple scenario runs in a single session, resetting state between runs. Standardized method naming and fixed related test cases.
