feat: select multiple threads for cleanup in UI

[hwc0x01]

Problem Can only delete threads individually now.

Success Criteria Would like to delete multiple threads at once.

Additional context None.

cc @hieu-jan we also need docs teaching users how to clear thread history directly via folder

Just a section on Bulk deletion in folder would be good.

FYI @hwc0x01 you can bulk delete the threads folders via this guide: https://jan.ai/guides/chatting/manage-history/#managing-threads-via-folders

Thanks, I've been doing that but this feat req is for convenience and more basic users.
