[feat] Add async tasks to calculate segmentation evaluation scores.

[kuang-da]

Currently, calculating segmentation evaluation scores takes about 1.5–3× longer than other steps in the main module. By default, we recommend keeping it enabled so that segmentation and cell profiling results are available as soon as possible. However, it would be preferable to run the segmentation evaluation as an asynchronous task, update the HTML report once results are ready, and avoid delaying the overall workflow.
