Normalize script input; update OpenAPI types

- Update OpenAPI annotations in ScriptController to declare 'data' and 'config' as objects instead of arrays.
- Add getRequestArray() to normalize script inputs: decode JSON strings to arrays, detect list payloads and unwrap single-element list objects (e.g. [{}] or [{"key":"value"}) to an associative object, and return an empty array for unsupported forms. This prevents the script microservice from rejecting list-shaped payloads (422) and enforces consistent request shapes.
