fix: Keep highlight when page is zoomed in/out

[ahmetkursatd]

This change prevents zoom-triggered PDF reloads and make highlight navigation optional. The document viewer no longer reloads the PDF when zoomLevel changes, and highlight creation now accepts an an option to suppress page navigation during highlight recreation. This keeps the viewer on the current page while still refreshing highlights after zoom. Changes are in document-viewer.tsx and pdf-highlighting.ts.

Summary:

• Stop full PDF reloads on zoom by removing zoomLevel from the render effect deps in document-viewer.tsx.
• Extend createRectangleHighlight to accept shouldNavigateOnMatch and wire it from the viewer to avoid forced page jumps during highlight recreation.
• Align highlight calls with the new options-object signature.
