refactor: Update ZenThemeImporter and ZenThemeMarketplaceParent

Browse source 
Improve page load performance by adding lazy loading for images in the ZenThemeImporter and ZenThemeMarketplaceParent files. In ZenThemeImporter, the observer method has been updated to call the rebuildThemeStylesheet function instead of updateStylesheet. Additionally, the sss.loadAndRegisterSheet method has been modified to use the AGENT_SHEET parameter instead of USER_SHEET. In ZenThemeMarketplaceParent, the console.info statement for downloading files has been removed and replaced with a console.error statement for error handling. These changes optimize the loading of images and enhance the overall user experience.
