Subject: [PATCH] Replace DxPdfViewer with DxReportViewer for PDF handling

Replaced `DxPdfViewer` with `DxReportViewer` to unify handling of
both PDF and report rendering. Removed conditional logic for
`PdfBytes` and directly initialized `XtraReport` with PDF content
using `XRPdfContent`. Simplified `OnInitializedAsync` to fetch
PDF content, create a report, and store it in `ReportStorage`.
Removed unused fields (`PdfViewerUrl`, `PdfBytes`, and
`SignedPdfBytes`) and redundant code related to PDF handling.
