manage_status_page

    IMPORTANT — Publishing a maintenance on the Status Page:
        To publish a maintenance, you MUST provide either change_id or
        maintenance_window_id. The rules are:

        1. If the Change already has a maintenance_window (check via
           manage_change action='get' → maintenance_window.id), use change_id.
        2. If the Change has NO maintenance_window (maintenance_window is
           empty {}), you MUST first create a Maintenance Window using
           manage_maintenance_window action='create' with name, description,
           start_time, end_time, AND change_id (to auto-associate the MW
           with the Change). Then use the returned maintenance_window_id here.
        3. You can also use maintenance_window_id directly if you already
           know the MW ID.

        Required fields for create_maintenance:
          - title, description, started_at, ended_at, impacted_services
          - impacted_services format: [{"id": <service_component_id>, "status": 5}]
            status values: 1=Operational, 5=Under maintenance, 10=Degraded,
            20=Partial outage, 30=Major outage

            Check via manage_change get → if maintenance_window is empty {},
            use manage_maintenance_window to create one first, then pass
            maintenance_window_id instead.
        maintenance_window_id: Maintenance Window ID — maintenance CRUD from a MW.
            Use this when the change has no built-in MW, or for standalone MW
            publishing. Create a MW first via manage_maintenance_window action='create'.
