fix: set valid fromBlock filter to check creation tx hash from the logs

[kiriyaga-txfusion]

What 💻

• Set valid fromBlock filter to check creation tx hash from the logs

Why ✋

• With the new version of zksync-ethers v5, specifying fromBlock as 0 is no longer valid, and filtering doesn't have the desired effect. To address this, we need to set the fromBlock filter to 'earliest' to effectively search for the creation transaction hash.
