[Bug]: Earn is not showing the same tokens to deposit compared to previous release after upgrade

### Describe the bug

Earn is not showing the same assets on the select token to deposit modal as it was on the previous version for the same account. This release is showing fewer tokens to deposit, only showing ETH on Ethereum. Previous release also showed USDC on Base and Linea.

UPDATE: Expected tokens to deposit showed up after several minutes, maybe a few hours on this build.

### Expected behavior

- Should show all earn eligible tokens to select on select token deposit modal

### Steps to reproduce
```gherkin
Feature: Deposit Tokens to Earn After Upgrade
As a MetaMask Mobile user
I want to deposit tokens to Earn after upgrading the app
So that I can continue using the same tokens I had available before the upgrade

Background:
Given I am logged into MetaMask Mobile
And I have upgraded to the latest app version

@earn
@deposit
@post-upgrade
Scenario: Available tokens persist in deposit selection modal after upgrade
Given I am on the Wallet home screen
And I have ETH and USDC tokens in my wallet

When I navigate to "Earn"
Then I should see the token selection modal
And I should see "ETH" available to deposit
And I should see "USDC" available to deposit
And all my pre-upgrade tokens should be available for selection

When I select "ETH" from the token list
Then I should be on the Earn deposit screen
And "ETH" should be selected as the deposit token
```
