[BUG] Sequencer send can't send tx to L1

[zjg555543]

Bug Report

Description

1. When the sequencer account has no balance, it becomes stuck and unable to send to L1.
2. Even after providing sufficient balance, it remains stuck and cannot send.

To Reproduce

1. Run all components with kurtosis.
2. Transfer the balance of the sequencer sender's account to 0, making it unable to send transactions.
3. At this point, the CDK sequencer sender fails to send transactions, which are stored in the database with a failed status.
4. Transfer funds back to the sequencer sender account, expecting the transactions to be sent to L1, but they still fail.

Root case

errors.Is can't be checked with two different error types, otherwise it will always return false.
The current bug is caused by the ethtxmanager.

Similar comparisons have also been found in both cdk.

In fact, will this code never be executed? I'm not quite sure.
