Enhanced signature navigation and rendering logic in `pdf-viewer.js`:
- Added `_renderLock` to prevent concurrent page renders.
- Refactored `renderPage` and `queueRenderPage` for stability.
- Updated `goToNextSignature` to support cross-page navigation.
- Filtered out applied signatures during rendering and navigation.
- Improved handling of applied signatures visibility per page.
Updated `EnvelopeViewer.razor`:
- Added `OnPageChangedBySignatureNav` to handle page changes triggered by signature navigation.
Improved code readability, added comments, and removed outdated logic to ensure smooth transitions and better user experience.
