refactor(cli): reorganize parameters module and eliminate code duplication

[ryanmccann1024]

Description:
This PR completes the CLI organization refactor by restructuring the parameters module for better maintainability and eliminating code duplication across CLI entry points. The work builds on previous CLI modernization efforts to achieve perfect pylint compliance and improved code organization.
