refactor: Create Message Layer (#messages) for Centralized Outputs

[jotanarciso]

Description:
To improve maintainability and localization of strings used for output messages in the project, it is beneficial to introduce a dedicated message layer. This message layer will serve as a centralized storage for all the strings used in the project's output messages, making it easier to manage, update, and support multiple languages or localization.

The goal of this issue is to establish a message layer that stores all the strings used for output messages in a centralized manner. This will provide a more organized and maintainable approach to managing strings, making it simpler to update and translate them as needed.
