`dbt source freshness` logs are not associated with the enclosing task

Bug summary

When calling PrefectDbtRunner.invoke(['source', 'freshness', ...]) inside a Prefect task, logs from source node events appear in the flow run only — not in the task that called invoke().

Steps to reproduce

@task           
def run_source_freshness():                                                                                                                                                                   
    runner = PrefectDbtRunner(settings=project_settings)                                                                                                                                      
    runner.invoke(['source', 'freshness', '--target', env])                                                                                                                                   

Source freshness logs are missing from the run_source_freshness task logs and appear only at the flow level.

Expected behavior
Logs produced by PrefectDbtRunner.invoke() should appear in the enclosing task run (and propagate to the flow as usual).
