Replace Ollama docx import with mammoth HTML conversion

Remove all AI processing from the import-docx endpoint. Instead:
- Convert the .docx to HTML with mammoth.convertToHtml (preserves
  bold, headings, lists, etc.) — the result goes straight into the
  item body and renders in the lesson viewer
- Extract raw text in parallel to pick the document title from the
  first non-empty line
- No external services, no AI, works on the deployed server
