Updated the document signing system to use a unified Blazor Auto (Server+WASM hybrid) frontend. Replaced client-side API calls with server-side authentication and data loading via `EnvelopeReceiverAuthorizationService` and `EnvelopeReceiverPageDataService`.
- Updated `/envelope/{key}` route to use MediatR for data loading.
- Integrated PDF.js 3.11.174 for rendering with configurable quality.
- Removed iText7 dependency due to GPL license issues.
- Introduced per-envelope cookies for receiver authentication.
- Cached signatures now loaded from distributed cache.
- Replaced redundant client-side API calls with server-side logic.
- Improved security and performance with server-side authorization.
These changes streamline the workflow, enhance security, and align the system with modern Blazor Server practices.
