Refactor API methods to return bool for success status

Updated `CreateAsync<T>`, `UpdateAsync<T>`, and `DeleteAsync<T>`
methods to return a `bool` indicating success instead of
`HttpResponseMessage`. Added `using` statements to ensure proper
disposal of HTTP content and response objects. Simplified the
interface for better usability by leveraging `IsSuccessStatusCode`
to determine operation success.
