Refactor: Move All Imports to the Top of Files

[Gfecito]

This PR refactors the existing Python code by moving all imports to the top of each file, following the best practices recommended in the official Python documentation (PEP 8).

This change aims to enhance code maintainability, readability, and may improve performance by preventing redundant imports when functions are called repeatedly.

Key Changes:

• Consolidated Imports: All imports have been moved to the top of their respective files to comply with Python's standard practices.
• Adherence to Best Practices: The code now follows the guidelines for import statements, making it more consistent and easier to maintain.
• Potential Performance Gains: By moving imports out of function definitions, we avoid re-importing modules multiple times during repeated function calls, potentially enhancing runtime efficiency.

Next Steps (Before Merge):

• Establish Comprehensive Test Bed: Before merging, set up a thorough testing suite to cover all critical paths and ensure that moving imports has not inadvertently caused regressions or other issues.
• CI Integration: Integrate the test bed into the continuous integration (CI) pipeline to automate testing and enforce code quality standards.

Next Steps (Post Merge):

• Additional Refactoring Opportunities: As a follow-up, consider reducing the amount of top-level code by abstracting logic into well-defined classes and functions. This can improve maintainability, testability, and scalability of the codebase.

Important Note:

Please ensure that the test bed is in place and passes all critical tests before proceeding with the merge.

There may be other imports than we can remove, but its outside of the scope of this change.
It'd be prioritary to set the test bed and reduce repetition first, and only then hunt these down.
