Description
The stream flow control window is currently limited to 10 MB. This limits transfer performance on connections with BDPs higher than that. We should use a significantly higher value than that. 50 MB seems like a better choice for well-connected servers.
This should be ok since window increases are limited by the resource manager.

Research direction
Start by locating the QUIC stream flow-control window and the resource manager that constrains window increases. Confirm how the current 10 MB limit is applied, then verify that a 50 MB window improves high-BDP transfers without bypassing resource-manager limits.
