[QA] BNB token balances fail to load due to RPC 401 error (API key disabled)

[agodlevska]

Describe the current behavior in detail

Environment:

• OS: macOS Tahoe 26.4.1
• Wallets: Petra
• Browser: Google Chrome Version 147.0.7727.102 (Official Build) (x86_64)
• https://github.com/wormhole-foundation/wormhole-connect/releases/tag/development%406.0.0-beta.1

Steps to Reproduce:

1. Connect your wallet.
2. In the From (or To) section, select the BNB network.
3. Observe the token balance display in the UI.
4. Open the browser's developer console.

Expected Results: The token balance should fetch and display successfully. The default RPC endpoint configured for the BNB network should be functional and not return disabled key or authentication errors.

Actual Results: The token balance fails to load and does not display in the UI. The console throws a 401 Server Error indicating that the API key is disabled for the default RPC endpoint (https://bscrpc.com).

Failed to fetch balance for token ["Bsc","0x1f29fAD000255BF49D72803b2A8FaC8e31947eF8"] Error: server response 401  (request={  }, response={  }, error=null, info={ "requestUrl": "https://bscrpc.com", "responseBody": "{\"error\":\"message: API key disabled, json-rpc code: -32051, rest code: 403\"}", "responseStatus": "401 " }, code=SERVER_ERROR, version=6.13.5)
