Fix document analysis: switch to unpdf + mammoth for PDF/Word parsing

pdf-parse v2 requires DOMMatrix (browser API) which fails in Node.js. Replaced with unpdf (serverless PDF.js build) for PDFs and mammoth for Word .docx files. Also fixed the same broken pdf-parse usage in file-content-extractor.ts used by AI filtering. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
