Subject: [PATCH] Fix PDF export/print margins: respect Page Setup and remove
 double margins

The printInfo method hardcoded all four margins (top/bottom 50pt, left/right
0pt), overriding whatever the user configured via File > Page Setup. This
made the Page Setup dialog effectively non-functional for margin control.

Additionally, all CSS stylesheets added body padding/margin of 2cm in their
@media print blocks, which compounded with the NSPrintInfo margins to create
unpredictable whitespace.

This commit:
- Removes hardcoded margin values from printInfo, allowing NSPrintInfo
  (controlled by Page Setup) to be the single source of truth
- Zeros out @media print body padding/margin in all 6 bundled stylesheets
  to prevent double-margin compounding

Users can now control PDF/print margins via File > Page Setup (Cmd+Shift+P).
