[Feature Request] V3 : Delete old Task after a amount of time eg 1 Month & possibility delete all task at once

In V3, old tasks can only be deleted page by page, with a maximum of 25 tasks per page.

Unlike V2, many scheduled tasks are created automatically (for example, for email checks), which can result in hundreds or even thousands of task entries accumulating over time. In my case, I recently had approximately 2,700 task entries across 20 pages.

Since only 25 tasks can be deleted at once, cleaning up old entries is a very time-consuming process.

I would like to suggest one or both of the following improvements:

1. A configurable retention policy that automatically deletes tasks older than a specified number of days.
2. A “Delete All” option that allows users to remove all visible tasks in a single action.

Either of these features would significantly improve task management and reduce manual cleanup effort.
