Testing failure handling of in Bridge message processing

[dantaik]

Describe the feature request

We can change Horse token to have a likelihood of 50 to fail when transfer tokens. Then it will enable us to test the source/destination bridge's error handling with the Bridge UI.

• Daniel, an ERC20 token is added for testing purpose: test(protocol): add an ERC20 token to test bridge #13130
• David, could you please make sure this ERC20 token is deployed on our devnet (we will not deploy it on public testnet) feat(protocol): deploy a test ERC-20 token to test bridge #13132
• Jeff, could you please enable this token in our bridge config?

Deployed and verified: https://l1explorer.internal.taiko.xyz/address/0x1B5Ccd66cc2408A0084047720167F6234Dc5498A , also added token address to the internal devnet doc: https://github.com/taikoxyz/k8s-configs/blob/main/docs/internal-devnet-user-guide.md.

I don't see any bridge test failing, close this one for now.

Does it mean BullToken can be removed from our codebase?
