Update CI test commands in workflow

Replace `uv sync --all-extras` with `uv pip install --system ".[tests,mcp]"` to install the project's test extras, and run tests with `pytest -vv` instead of `uv run pytest` to produce more verbose test output. These changes ensure CI installs the required extras and yields clearer test logs.
