fix: remove m2r and clean up deprecated Sphinx configuration

m2r is unmaintained and incompatible with Sphinx >= 7. No .md files
exist in docs/, so it was unused. Remove it from both the Sphinx config
and project dependencies.

Also removes deprecated html_theme_path override (interferes with
sphinxcontrib-jquery registration), reference to non-existent
theme_overrides.css, and orphaned custom stylesheet comments. Wraps
pre-existing long lines in conf.py to satisfy flake8.
