feat: automates the host-style tests in the pipeline

Adds a GitHub Actions workflow to run the `host-style` tests inside Docker containers. The tests are executed in a Docker environment using `Docker Compose` with three containers: one for running the tests, one for setting up the server, and one using the `dnsmasq` image for `DNS` server configuration.
