Regenerated against UI API 1.6.0: every operation has an operationId and the standard error responses (BasicErrorResponseV1: error, code, message, fieldErrors, traceId); the extension's own error schema is kept but deprecated; hand-written error bodies go through QJavalinUtils so they carry code/message/traceId. Extension MINOR bumped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
