This commit introduces a detailed migration plan to replace the `PDF.js` rendering engine with `DxPdfViewer` in the receiver signing experience (`EnvelopeReceiverPage.razor`). The migration preserves the existing signing workflow and behavior while introducing a new rendering layer. Key changes: - Replaced `PDF.js` rendering surface with `DxPdfViewer`. - Preserved page-level orchestration for authorization, document loading, signature handling, and toolbar interactions. - Introduced a custom overlay adapter for signature placeholders and applied signature overlays. - Centralized page/zoom geometry acquisition for overlay alignment. - Maintained signature navigation logic and thumbnail sidebar behavior. - Updated `pdf-viewer.js` to separate engine-specific logic and adapt it for `DxPdfViewer`. - Updated styles in `envelope-viewer.css` to support the new viewer. This migration ensures that all existing workflow behaviors remain functional, including navigation, zoom, signature placement, and validation, while transitioning to the new rendering engine.
