[Bug]: Clicking "Confirm" should route to Activity Tab

### Describe the bug

When funding a Perps trading account the user completes a transaction by clicking on the "confirm" which initiates the transaction. After clicking on this button the user is shown the main perps page again as they await their deposit.

The user needs to click on activity tab to see the progress of their bridge transaction and know their funds are on the way.

### Expected behavior

Take the user directly to the activity tab so that they can see the progress of their transfer.

Start by reproducing the Perps Add Funds flow on iOS, following the confirmation action described in the issue. Trace the navigation from confirmation to the Perps home page and identify the existing Activity tab route. Done means confirming a deposit opens Activity directly and shows the bridge transaction progress.
