Failed flag should be cleared even if there is no fatal error

We've seen a few times subgraphs that are syncing fine, but have the failed flag set and no fatal error. I'm not sure how this happens, it probably shouldn't, but one thing we can easily address is that the unfail logic is not clearing the failed flag in this situation.

Here it is assuming that if there is no fatal error then the subgraph is not failed:

store/postgres/src/deployment_store.rs の1437〜1442行付近を読み、unfail ロジックを追ってください。subgraph に fatal error がないにもかかわらず failed flag が設定されたままの場合の動作を確認してください。その状況でその flag がクリアされれば完了です。
