fix(client): prevent client freeze when calling async from sync methods

[hamzamahmood]

What

• Applied ConfigureAwait(false) to await calls in async methods.
• Ensured proper async handling to prevent UI or request thread blocking.

Why

• Calling async methods from synchronous code without ConfigureAwait(false) can cause deadlocks, especially in UI or ASP.NET applications.
• This fix ensures that awaited tasks do not attempt to resume execution on the original synchronization context, preventing the client from freezing.
