Add support for downloading all document libraries on a site

- New get_all_drives() fetches all drives from a SharePoint site
- main() loops over all drives when DOCUMENT_LIBRARY is empty, placing
  each library in its own subfolder under LOCAL_PATH
- MSAL force_refresh now catches TypeError/ValueError for compatibility
  with older MSAL versions that don't support the parameter
- GUI: "Download alle biblioteker" checkbox disables Library Navn and
  Mapper fields; load_settings restores checkbox state from config
