feat(l1,l2,replay): mempool max size parameter

[gianbelinche]

Motivation
We want to make the mempool max size a parameter

Description
Adds the mempool max size as a parameter to ethrex command

Closes #4600

[Copilot]

Pull Request Overview

This PR adds a configurable mempool max size parameter to the ethrex command and blockchain components. Previously, the mempool size was hardcoded to 10,000 transactions.

• Adds --mempool.maxsize CLI argument with default value of 10,000
• Updates all blockchain constructor calls to accept the max mempool size parameter
• Replaces hardcoded MEMPOOL_MAX_SIZE constant with configurable parameter
