chore(gen): refresh generated schemas after Client.Secret comment drop

Commit d8b9f535 dropped the trailing comment on model.Client.Secret but did not regenerate the openapigen output, leaving a stale "MTProto FakeTLS secret" description in schemas.ts and openapi.json. Rerun make gen to bring the generated files back in sync with the source.
