- Introduces new `JavascriptWebApi` and `Payload` options for enhanced serialization in Web API requests.
- Ensures consistent property naming and case sensitivity by utilizing appropriate `JsonStringEnumConverter` settings.
- Provides a dedicated option for payload serialization with case insensitivity and improved defaults.
