    Downgrade H2 stream error log (#13298)
    
    Malformed HTTP/2 parse errors can hit this path during normal
    bad-client traffic, and logging each one at ERROR keeps diags noisy.
    PR #13059 now emits transaction log entries for these malformed
    requests, so operators can diagnose the rejected request without this
    default error log noise.
    
    This downgrades the stream creation failure message to the existing
    HTTP/2 session debug path. Operators can still enable the http2_cs
    debug tag when they need the protocol-level detail.
