feat(ansible): a run's scope reads as the target or group it names

#5014 "Ansible run scope is shown as a raw id"

- inventory_gen.describe_scope / scope_labels turn "steward:target:<uuid>"
  into "target web-1", "steward:group:<uuid>" into "group Docker Swarm",
  and a deleted one into "target abcdef01 (deleted)".
- MCP run and schedule rows carry scope_label beside the stored scope; the
  ansible.run.started audit detail records it too.
- The web run page and schedules table show the name, with the stored
  scope as the tooltip.
