Fix: report_content in to_dict, single worker, hide stale preview

- Add report_content to Research.to_dict() — fixes translate-only cache
  showing only summary instead of full translated report
- Dockerfile: --workers 1 — fixes progress bar dropping to 0% on Fly.io
  (in-memory progress_tracker not shared between workers)
- Hide preview card once analysis starts (no longer stale)
