Pull Request Overview

• Updating DesktopCrossPasteModule to bind new marketing paste models when marketingMode is enabled.
• Refactoring PasteSearchViewModel into an abstract class and adding dedicated implementations for marketing and general paste searches.
• Introducing new classes for managing marketing paste data and updating paste item models to handle an optional basePath.
