fix: update performLCERequest for LCEssentials 2.0.2 API.request signature

LCEssentials 2.0.2 replaced request(url:params:method:headers:jsonEncoding:debug:)
with request(url:method:body:pathParams:headers:debug:timeoutInterval:networkServiceType:persistConnection:).
The pre-encoded params Data is now wrapped in RawBody to preserve the same
application/json Content-Type behavior that jsonEncoding: true used to set.
