Add Language Selector component to footer

Browse Source 
Introduced a Language Selector component (`LanguageSelector.razor`) to enable users to switch between German, English, and French. The component includes a dropdown UI with flag icons and language labels, along with logic for toggling the dropdown and changing the app's culture.

Injected `IJSRuntime`, `NavigationManager`, and `CultureService` into the component to handle culture changes and navigation updates.

Updated `MainLayout.razor` to include the Language Selector in the footer. Refactored footer layout in `MainLayout.razor.css` to use flexbox for better alignment and spacing.

Added styles for the Language Selector in `app.css` to ensure a clean and responsive design. Integrated the `flag-icons` library in `index.html` to display flag icons for language representation.
