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.

まず @asgardeo/javascript パッケージの認証および初期化フローを追跡し、SCIM Schemas、organizations、Me エンドポイントへの呼び出し箇所を特定します。認証フローが引き続き機能する状態で、開発者がこれらの追加の呼び出しを無効に設定できれば完了です。パッケージのテストでこの動作を検証している箇所に、カバレッジを追加または更新してください。
