Pull Request Overview

This PR enhances the Column class to accept Any/Object parameters for several comparison and arithmetic operations instead of requiring only Column parameters. The enhancement allows users to pass literal values directly without explicitly wrapping them with lit().

Key changes:

• Modified Column method signatures to accept Any (Scala) or Object (Java) instead of just Column types
• Added comprehensive test coverage for the new parameter types
• Refactored duplicate code by introducing a shared toScalaColumn utility method
