fix(deps): regenerate requirements.txt to include redis

redis>=5.0.0 was added to pyproject.toml and uv.lock but requirements.txt
was never regenerated. The Dockerfile installs deps from requirements.txt,
so redis was absent from the Docker image, causing a ModuleNotFoundError
at runtime when REDIS_HOST_PORT is set.
