Chaim 476c2fc5d1 feat(upload): accept legacy .doc, convert via LibreOffice in container ...

Legacy Hebrew .doc precedents (e.g. nevo.co.il CP1255 OLE2) can now be
uploaded directly through the precedent-library, missing-precedent, and
training upload paths — the frontend already advertised .doc but the
backend gate rejected it before reaching the extractor.

- web/app.py: add .doc to ALLOWED_EXTENSIONS (covers all paths that share
  the set: precedent library, missing-precedent, training).
- Dockerfile: install libreoffice-writer-nogui (no X11/Java) so the
  extractor's existing _extract_doc LibreOffice conversion works in the
  Coolify container (was missing → would fail at runtime).
- extractor.py: isolate the LibreOffice user profile per call to avoid a
  profile-lock failure on concurrent .doc conversions.

Verified in python:3.12-slim (prod base): .doc→.docx→text yields text
byte-identical to a native Word .docx save (103 paragraphs, 24,341 chars).
