Add Escape key navigation and update status panel behavior

Added MainGrid KeyDown handler to support Escape key for back navigation in ContentFrame. Updated ClearStatus_Click to collapse DimmerStatusPanel. Introduced new XAML namespace for custom views and included commented-out code for future SmokeViewQueueGrid integration. Minor XAML improvements for maintainability.
