Track wire bytes separately from decompressed stream bytes

Browse Source 
The stream stats were showing decompressed data sizes, not actual wire
bandwidth. This change adds wire byte tracking by disabling automatic
gzip decompression in the HTTP client and wrapping the response body
with a counting reader before decompression. Both wire (compressed) and
decompressed bytes are now tracked and exposed in the API responses.
