TekH 7d0c5a0ee5 Improve error handling and logging for envelope receiver
Added a null check in `EnvelopeReceiverPage.razor` to log a warning when `_envelopeReceiver` is null. Updated `ReportViewer.razor` to wrap `EnvelopeReceiverService.GetAsync` in a `try-catch` block, logging `HttpRequestException` errors and allowing the UI to handle null values gracefully.

Enhanced `EnvelopeReceiverService.GetAsync` to throw detailed `HttpRequestException` on API failures, including status code and reason phrase. Added `using System.Net;` to support HTTP-related classes. Updated method documentation to reflect the new behavior.

These changes improve error diagnostics, logging, and maintainability across the codebase.
