Create desktop app with MudBlazor and Blazor Hybrid matching test app functionality

[jregnier]

Develop a desktop application using MudBlazor and Blazor Hybrid that replicates all current functionality of the existing test applications. The new app should:

• Be built with MudBlazor for UI components and Blazor Hybrid for native desktop support
• Mirror every feature and workflow present in your other test apps, ensuring complete feature parity
• Maintain a similar look and feel for consistency and ease of maintenance
• Adhere to best practices for Blazor Hybrid development
• Include documentation on the setup and running of the new desktop app
• Include a light mode / dark mode toggle

Deliverables:

• Source code for the full-featured desktop app using MudBlazor and Blazor Hybrid that matches the test app functionalities
• Documentation for setup, building, and running
