Yaojia Wang	4c7fc3015c	fix: add PDF magic bytes validation to prevent file type spoofing ... Add validation that checks PDF files start with '%PDF' magic bytes before accepting uploads. This prevents attackers from uploading malicious files (executables, scripts) by renaming them to .pdf. - Add validate_pdf_magic_bytes() function with clear error messages - Integrate validation in upload_document endpoint after file read - Add comprehensive test coverage (13 test cases) Addresses medium-risk security issue from code review.	2026-02-03 22:28:24 +01:00
