🔇(backend) silence noisy request summary info logs

The request summary info logs were spamming the log stream, making
around 46% of the total volume, without carrying any exploitable
information.

Silence them so the remaining logs are easier to explore and cheaper
to store; roughly halves the overall log volume.
