Subject: [PATCH] Enhance globalization and error handling support

Added support for culture-specific globalization in the Blazor WebAssembly project by disabling invariant globalization and enabling the loading of all globalization data.

Improved error handling in `ReportViewer.razor` by wrapping the `ExportToAsync` method in a `try-catch` block to handle export failures gracefully. Updated user-facing messages to provide clearer feedback in case of errors.
