feat: add print button that replaces page content for printing

Browse source 
Instead of trying to print iframe directly, the print button:
1. Collects all styles from the iframe
2. Replaces the main page content with iframe content
3. Triggers window.print()
4. Reloads the page to restore the app

This ensures the PagedJS rendered content prints correctly.
