fix(pgplugin): log JSON encode errors in writeJSON

writeJSON ignored the error from json.NewEncoder(w).Encode(body). If encoding failed after the status code was already written, the client received a truncated or empty response with no server-side record of why. Log the error so operators can diagnose serialization issues. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
