Remove test log display from docs and clean up conf.py

[shegazyy]

The DisplayTestLogs Sphinx directive collected bazel-testlogs at build time and embedded them in the verification report. This had two problems:

• The directive was registered in the local conf.py which is not executed in the score reference integration (docs-as-code), making it a no-op in official releases.
• The project has decided not to include test logs in documentation.

Remove the directive class, its registration, and the "Test Log Files" section in statistics.rst. Also drop the now-unused docutils imports.

Closes #266
