feat: add isTokenEndpointIpHeaderTrusted field to Client

Add support for the is_token_endpoint_ip_header_trusted property
in the Client class with proper JavaDoc documentation and test coverage.

- Add isTokenEndpointIpHeaderTrusted field with @JsonProperty annotation
- Add getter and setter methods with JavaDoc following class conventions
- Update ClientTest with serialization and deserialization tests
- Verify all tests pass successfully
