refactor: improve code formatting and consistency across multiple files

- Standardized import statements and removed unnecessary line breaks for better readability in various components.
- Enhanced error handling and logging in the useElectronPrinter hook.
- Updated sample data formatting in AgGridShowcase for improved clarity.
- Refactored JSX elements for consistent indentation and structure in LandingSample, AuthPage, and EventsPage components.
- Consolidated and simplified conditional rendering logic in several components.

These changes aim to enhance code maintainability and readability throughout the project.
