[Bug]: Staking Confirmation Screen Blockies/Jazzicon not displaying for user's account

Nobody has claimed this yet.

**Describe the bug**

Location: On the staking, unstaking, and claim confirmation screens, under the "Advanced details".

Bug: There's a `"?"` icon displayed to the left of a user's account.

Typically we use the `"?"` icon next to unknown addresses (accounts/contracts)

**Expected behavior**

Instead of a `"?"` icon there should be a blockie or jazzicon (based on user settings).

**Steps to reproduce**

Prerequisite: Have some ETH to stake

1. On the Ethereum details screen, click "stake" or "stake more"
2. Enter a valid amount to stake and click to next screen
3. On the stake confirmation screen, click the "Advanced details" section header to unveil some additional rows
4. Notice that the "Staking from" row containing the current account has a `"?"` icon next to the address

**Error messages or log output**

```shell

```

**Detection stage**

During release testing

**Version**

7.44.0

**Build type**

None

**Device**

iPhone 11 (iOS v.18.3.2)

**Operating system**

iOS

Reproduce the issue on the staking confirmation flow, including stake, unstake, and claim screens, then inspect the Advanced details rows and the account icon rendering. Done means the current user's account shows a blockie or jazzicon according to user settings instead of the unknown-address "?" icon.
