Add comprehensive debug logging for Noop record processing
- Track Produce v2+ request reception with API version and request body size - Log acks setting, timeout, and topic/partition information - Log record count from parseRecordSet and any parse errors - **CRITICAL**: Log when recordCount=0 fallback extraction attempts - Log record extraction with NULL value detection (Noop records) - Log record key in hex for Noop key identification - Track each record being published to broker - Log offset assigned by broker for each record - Log final response with offset and error code This enables root cause analysis of Schema Registry Noop record timeout issue.
