chore(slicer-api): bump BAMBU_VERSION default to 02.07.01.57

  Tracks the orca-slicer-api Dockerfile change that switched the sidecar
  from the (no-longer-published) Fedora AppImage to the Ubuntu 22.04
  AppImage. The default in .env.example and slicer-api/docker-compose.yml
  now matches the new build path; users running the sidecar should
  `docker compose --profile bambu build --no-cache bambu-studio-api &&
  docker compose --profile bambu up -d` after pulling this change.
