Use versioned URLs for static assets

Browse Source 
Updated `EnvelopeViewer.razor` to use versioned URLs for CSS and JS files via the new `AppVersionService`, enabling cache busting.

Introduced `AppVersionService` to generate versioned URLs based on the application version retrieved from assembly metadata.

Registered `AppVersionService` as a singleton in `Program.cs` for dependency injection.
