docs: fix OpenAPI documentation for setDocMdpConfig endpoint

Add proper PHPDoc annotations:
- Detailed parameter descriptions for enabled and defaultLevel
- Complete DataResponse return type with status codes and schemas
- HTTP status code documentation (200, 400, 500)

Fixes OpenAPI generation errors.
