Refactor GetAsync methods to return deserialized data

Updated GetAsync methods in ProfileApi, RecActionApi, and
ResultApi to return deserialized objects of type <T> instead
of raw HttpResponseMessage, improving usability.

Added conditional compilation (#if NETFRAMEWORK) to handle
nullable return types (T?) for non-NET Framework targets,
ensuring compatibility across .NET versions.

Replaced direct Http.GetAsync calls with using blocks for
proper disposal of HTTP responses. Introduced response
handling and deserialization via ReCClientHelpers to
streamline processing and logging.

Updated XML documentation to reflect the new behavior and
removed redundant parameters.
