Simplify signed document viewer logic
Removed all signature capture and validation functionality, including the signature popup, JavaScript interop, and related backend logic. Simplified the `DxReportViewer` initialization to directly display the signed document. Added support for retrieving cached signatures via the `sid` query parameter. Streamlined error handling, logging, and page metadata. Cleaned up unused imports, constants, and methods to reduce complexity.
