Nitpick, simplification:
```suggestion
// Get new last verified batch number from L1
lastVerifiedBatchNumber, err := a.etherman.GetLatestVerifiedBatchNum()
```
* L2 to L1 withdrawal test
* Refactor tests to reduce complexity
* Bump `kurtosis-cdk` version to `v0.2.15`
* Improve CI by dumping enclave logs + files in kurtosis
