fix: correct ListOffsets v1 response format for kafka-go compatibility

- Fixed throttle_time_ms field: only include in v2+, not v1
- Reduced kafka-go 'unread bytes' error from 60 to 56 bytes
- Added comprehensive API request debugging to identify format mismatches
- kafka-go now progresses further but still has 56 bytes format issue in some API response

Progress: kafka-go client can now parse ListOffsets v1 responses correctly but still fails before making Fetch requests due to remaining API format issues.
