feat(viewer): add PrintMode for browser print/PDF export

Browse Source 
Adds RenderOptions.PrintMode flag. When true:
- view.js (table filters) is not loaded
- window.print() fires on page load
- @media print CSS hides filters, collapses grid to single column,
  adds page-break hints for section cards
