- Introduced a new `webFavicon` property in the AllSetting model to store the favicon data URL. - Implemented upload and delete functionality for the favicon in the GeneralTab component, including validation for file type and size. - Updated the backend to serve the favicon in the HTML head if set. - Added translations for favicon-related messages across multiple languages.
