Optimize PDF

Clean up and optimize PDF structure by removing unused objects and rebuilding the file.

Optimization rebuilds the PDF structure to reduce size and improve compatibility.
Many PDFs are already compressed: you may see no size change, especially on Low (best quality). High applies stronger image downsampling than Medium.
Privacy Note: Optimization runs on our server, but your file is never saved to disk. It's processed entirely in memory and deleted immediately after completion.
