Add support for signed PDF previews

Browse Source 
Integrated `PdfSignatureService` to enable fetching and previewing signed PDFs for completed envelopes. Updated `SenderPage.razor` to dynamically adjust popup headers and filenames based on the envelope's status. Enhanced `OpenPreviewAsync` to conditionally fetch signed or original PDFs.

Registered `PdfSignatureService` and DevExpress PDF Viewer in `Program.cs`. Implemented `PdfSignatureService` to handle API calls for retrieving signed PDFs with error handling.
