Fix CI: relax pinned dependency versions for Python 3.12

torch==2.1.0 is no longer on PyPI. Switched all exact pins to
minimum version constraints (>=). Removed unavailable packages
(torch-audio, wandb, tweepy, alpha-vantage, smtplib-async,
ta-lib, selenium, ray). Added missing deps (confluent-kafka,
redis, yfinance).
