This commit removes several navigation items from the `navData` array in `nav-config-dashboard.tsx`, including 'Dashboard', 'User', 'Blog', 'Sign in', and 'Not found'. The 'Product' item's `info` property has also been commented out. A commented-out section has been added to preserve the removed items for reference, and `#region` and `#endregion` comments have been introduced for better code organization.
