	var traceId [16]byte
	traceBytes, err := hex.DecodeString(string(dbTraceId))

### Steps to reproduce


### **Steps to reproduce**
```markdown
1. Configure Jaeger with the `v2` Elasticsearch storage backend.
2. Query a trace that originally had a 64-bit Trace ID (16 hex characters).
3. Observe that the returned trace data has a corrupted 128-bit Trace ID where the 64-bit value is shifted to the left and padded with zeros on the right (e.g., `[original_id]0000000000000000`).


### Expected behavior

When reading a 64-bit Trace ID from Elasticsearch, it should be mapped to the lower 8 bytes (right-aligned) of the `pcommon.TraceID` so that the trace ID accurately reflects `0000000000000000[original_id]`.
