Return trials to frontend only when they are used

還沒有人認領這個 Issue。

In the backend, an Experiment is stored together with its generated trials in memory, after an Experiment was created in the frontend.

For the Experiments list view we don't need the trials but they are still returned.

For many Experiments with large number of trials this leads to unnecessary transfer of information, slowing down the application, especially when the instance has limited resources.

We should only return (and even generate) the trials if a user opens the Experiment detail view.

追蹤 Experiments 如何為 frontend 列表檢視儲存和回傳，然後將該流程與 Experiment 詳細檢視進行比較。確認 trials 在哪裡產生和傳輸；完成標準是列表回應避免未使用的 trials，而開啟 Experiment 仍會產生並回傳 trials。
