Bug Report: USDT Transactions Appear in Activity but Not Reflected in Wallet Balance

Wallet: Common Extension Wallet (Testnet) Issue Type: Balance display not synchronized with transaction history

Description: In the Activities tab of the Common Testnet Wallet, I noticed two incoming transactions of USDT (Tether USD):

+46.87 USDT

+62.5 USDT

However, in the Tokens tab, the USDT balance remains at $0.00, and the tokens are not displayed at all.

Steps to Reproduce:

1. Open Common Extension Wallet on the Testnet.

2. Navigate to the Activities tab.

3. Observe incoming USDT transactions from address 0x5B49...7077.

4. Switch to the Tokens tab.

5. USDT balance still shows $0.00, despite the transactions being listed in activity.

Expected Behavior: After receiving USDT, the token should be reflected in the wallet balance under the Tokens tab.

Actual Behavior: USDT appears in the Activities log, but the balance does not update in the Tokens section.
