Downgrade H2 stream error log#13298
Merged

Malformed HTTP/2 parse errors can hit this path during normal bad-client traffic, and logging each one at ERROR keeps diags noisy. PR apache#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.

This reverts commit b79c0f8. Claude noticed that there are two messages like this, and this is the wrong one. I thought "new_transaction", chosen by Codex, made sense. But we really want the one in Http2ConnectionState::rcv_frame for inbound client errors.
