fix(ci): run pytest directly instead of via uv run

uv pip install --system installs packages into the system Python,
but uv run creates a separate project venv where pytest-cov is not
available. Fix by running pytest/playwright directly from the system
Python and consolidating deps into a single .[all,dev] install.
