Fix/remove splash

[mbsantiago]

This PR removes the PyInstaller-generated splash screen from the application.

Motivation

The splash screen was causing several issues:

• Crashes: It led to application crashes on macOS.
• Lack of Functionality: We were unable to display meaningful information on the splash screen.
• Visual Issues: The splash screen image appeared with a distorted border, leading to a poor user experience.

Given these issues, we decided that removing the splash screen was the best course of action.

Future Considerations

While we have removed the PyInstaller-generated splash screen, we may explore creating a custom splash screen implementation in the future. This would allow us to have more control over the splash screen's appearance and functionality, potentially providing a better user experience.
