fix: refactor typing imports and event loop handling

Replaced usage of typing_extensions with standard typing imports for TypedDict, ParamSpec, Concatenate, and related types where supported. Updated asyncio event loop initialization in Client to avoid deprecation warnings on Python 3.11+. Removed unused PY_310 constant and related conditional logic in utils.py.
