update_load_test

Edit an existing load test. A non-empty name renames it; any configuration field replaces the stored configuration and re-finalizes runnability — a simple test becomes generated once it has a journey (else draft), an advanced test rebuilds its k6 script. Send only a name (no config) to rename without touching the configuration.

The configuration fields are identical to create_load_test.
