Migrates `act_runner` configuration from shell-generated to an Ansible-templated `config.yaml`. This enables:
- Dynamic label provisioning, including `test-runner:docker://ubuntu:22.04`.
- Explicit configuration for joining the `iklimco-net` overlay network.
- Docker socket mounting for CI/CD jobs to interact with the Docker daemon.
Updates `setup/05-test-runner-ve-deploy-onkosullari.md` and other related documentation to reflect the new automated and integrated runner setup.
