Walkthrough

Added a GridHelperServiceInitListener class implementing VaadinServiceInitListener with a @CssImport annotation to ensure CSS styles are bundled during production builds. A service provider entry registers this listener for automatic discovery by Vaadin's service initialization mechanism.
