Add integration test: ensure roles including 'sys-service' define system_service_id

This test scans all roles for tasks including:
  - include_role:
      name: sys-service

If present, the role must define a non-empty 'system_service_id' in vars/main.yml.
Helps enforce consistency and prevent misconfiguration.
