Auto-Switch Wallet View to Last Transaction Network

### What is this about?

When a user processes a transaction from a dapp and returns to the wallet view, the wallet should automatically switch to the network on which the last transaction was made. This ensures that users immediately see the most relevant network context for their recent activity.

### Scenario

- Process a transaction from a dapp on a specific network.
- Navigate back to the wallet view.
- Observe that the wallet remains on the previous network instead of switching to the network used for the transaction.

Trace how a dapp transaction completion is recorded and how navigation returns to the wallet view. Identify the state or entry point that selects the active network, then verify that returning from a transaction selects its network and that the wallet displays the expected context.
