Introduced font size adjustment for grids via dropdown toolbar and CSS variable. Added JavaScript for dynamic font size changes. Replaced German umlauts with HTML entities for proper rendering. Refactored grid code and improved error/info message display. Enhances accessibility and user experience.
Implement dark mode support using a new ThemeState service that manages theme switching and integrates with DevExpress Blazor theming. Update App.razor to apply the theme globally, enhance MainLayout with a toggle button and dynamic CSS classes, and add dark mode styles to CSS files. Register ThemeState as a scoped service in Program.cs.
Added new Blazor Server project `DbFirst.BlazorWebApp` with core UI components, pages, and static assets. Updated solution file to include the project. Also added `bootstrap.min.css.map` to support CSS debugging in browser developer tools.
