Refactor AsgardeoReactClient initialization to fix the type issue

[NipuniBhagya]

Purpose

This pull request updates the initialization logic of the AsgardeoReactClient to improve how the periodicTokenRefresh configuration is handled. The main change is moving the logic for setting periodicTokenRefresh from the initializeConfig assignment to the object passed directly to the asgardeo.init call, ensuring the correct value is always used during initialization.

Configuration handling improvements:

• Moved the logic for determining periodicTokenRefresh from the initializeConfig property to the argument passed to asgardeo.init, ensuring that the most up-to-date value is used during initialization.
