feat(l2): enable command flags for l2 --dev

[tomip01]

Motivation

When running ethrex l2 --dev the sequencer flags are being ignored. We want to be able to configure the L2

Description

• Add a new populate_with_defaults function for L2 options. This function assigns default values to any Option<T> flags that are not provided when running l2 --dev, instead of leaving them as None.
• Update default implementation for ProofCoordinatorOptions to set proof_coordinator_qpl_tool_path as the one in the cli

[Copilot]

Pull Request Overview

Enable honoring CLI flags for l2 --dev by hydrating missing Option fields from Defaults and setting a default QPL tool path for the proof coordinator.

• Introduce populate_with_defaults across L2 option structs to apply defaults only for unset fields
• Set a default proof_coordinator_qpl_tool_path and wire population in the l2 --dev flow

Isn't this a Option::or()

Yes, nice catch.
