feat: support multi-formats — DOCX, images, ODT, RTF, TXT, HTML
Nouveau module format_converter.py : conversion automatique vers PDF avant anonymisation. Formats supportés : - PDF (passthrough) - DOCX (python-docx → texte → PDF) - ODT (odfpy → texte → PDF) - RTF (striprtf → texte → PDF) - TXT (texte brut → PDF via PyMuPDF) - HTML (BeautifulSoup → texte → PDF) - JPEG/PNG/TIFF/BMP (image embarquée → OCR docTR en aval) Nouvelle fonction process_document() : wrapper qui gère la conversion puis appelle process_pdf(). GUI mise à jour pour chercher tous les formats supportés (plus seulement *.pdf). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
