Update the number of torrents in the filters that are required based on the selected filter

[MrYuto]

Suggestion

Currently, the torrent count in the label of the filters updates entirely based on the properties of all torrents. So for example, if we select a category we still see the same torrent count as they had. I think we should also consider updating the torrent count based on the currently selected filters like categories, tags, and trackers.

Use case

This helps users quickly find out the status of their torrents based on a category, tag, and tracker.
