fix(docker): fix E2E torrent test and transmission-remote compatibility

- Add transmission-cli package (provides transmission-remote binary)
- Fix SETUPTOOLS_SCM_PRETEND_VERSION placement before RUN make install
- Fix PATH to use /root/.local/bin and include venv bin
- Switch TransmissionSession.add() from watch-dir polling to transmission-remote -a
- Remove --no-auth flag (unrecognized in transmission-remote 4.1.0)
- Add test_docker_torrent_downloads_wordlists E2E test
