Fix: CI Python test job not finding Rust modules

Changed wheel installation from `uv pip install` to direct pip execution
in the virtual environment. With uv's managed mode, packages installed
via `uv pip install` weren't properly visible to `uv run python` because
they aren't declared in the lockfile.

Changes:
- Use `.venv\Scripts\pip.exe` directly to bypass uv lockfile enforcement
- Add `--no-deps` flag since Rust bindings are standalone cdylib modules
- Add debug output to list downloaded wheels
- Add verification step to confirm classic* packages are installed
