Declare browser automation dependencies

[Mirochill]

Summary

• add the direct browser automation imports (selenium and undetected-chromedriver) to setup.py runtime dependencies
• add a Python 3.12+ setuptools dependency so environments without stdlib distutils still provide the compatibility layer needed by legacy dependencies
• keep the new dependency versions aligned with the existing requirements.txt
