fix: Wallet Auto-switches to Sepolia on First Access

[eduramme]

Description:

When first accessing the dApp, the wallet unexpectedly switches to the Sepolia network. This behavior is incorrect, as the network should not change automatically upon initial access.

Steps to Reproduce:

1. Open the dApp with a connected wallet.
2. Observe that the wallet network is automatically switched to Sepolia without user input.

Expected Behavior:

The wallet should maintain the user's pre-selected network and not automatically switch to Sepolia upon first accessing the dApp.

Actual Behavior:

The wallet switches to the Sepolia network upon initial access to the dApp.

Acceptance Criteria:

• The dApp no longer automatically switches the wallet to Sepolia on initial access.
• The wallet maintains the user's currently selected network upon opening the dApp.
