Provide Configuration to Disable Unnecessary Authentication Network Calls

### Current Limitation

During the authentication flow, the application triggers multiple network calls to external endpoints such as:

- https://api.asgardeo.io/t/{tenant}/scim2/Schemas
- https://api.asgardeo.io/t/{tenant}/api/users/v1/me/organizations?limit=10&recursive=false
- https://api.asgardeo.io/t/{tenant}/scim2/Me

These calls are executed automatically as part of the authentication/initialization process, even when the application does not require this data.

### Suggested Improvement

Suggested Improvement:

Introduce a configurable option to allow developers to disable these additional network calls during authentication.
