Refactor: object orientes architecture

[lcrojano]

Summary
We need to refactor the current codebase to adopt an Object-Oriented Architecture (OOA). This approach will help improve code organization, promote reusability, and make it easier to manage the complexities of our application. Additionally, we will implement Zod, a TypeScript-first schema declaration and validation library, to enhance data validation throughout the application.

Objectives
Refactor the Existing Code:

Transition the current architecture to an object-oriented design. This includes defining clear classes, encapsulating related data and behaviors, and implementing appropriate inheritance and polymorphism where necessary.
Identify modules or functions that can be grouped together into cohesive classes.

Implement Zod for Data Validation:
Integrate Zod into the application for robust schema validation. This will ensure that data conforms to defined structures and types before processing.
Create schemas for key data models and replace any existing manual validation logic with Zod schemas.
Ensure that error handling is incorporated, providing clear feedback for any validation failures.

Acceptance Criteria
The codebase follows an object-oriented architecture with clear class definitions and appropriate encapsulation.
All existing data validation logic has been replaced with Zod schemas.
Comprehensive unit tests are implemented to verify that the new architecture and validation logic function as expected.
Documentation is updated to reflect the changes in architecture and validation processes.

Benefits
Improved code maintainability and scalability through OOA principles.
Enhanced data integrity and validation robustness using Zod, reducing the risk of runtime errors due to invalid data.
