The fundamental problem you have is that QoS in the inbound direction (in to your router) to control traffic headed in your direction is relatively useless.

The congestion is occurring at the egress of the ISP device to which your Router attaches. That ISP interface has no relevant QoS applied - it is most certainly a FIFO queue. Thus if the bittorrent end points are sending you data faster than your HTTP end point, bittorrent wins in a classic FIFO queue and your HTTP download is starved.

This is a very common problem in almost every home networking setup. Bittorrent can easily starve not only SSH or RTP traffic, but VoIP traffic as well.

Use your Bittorrent software's built in rate limiting to cap up and down speeds at a rate lower than what is available.
