apollo_versioned_constants: reduce block gas_target 1.5B -> 1.04B (SNIP-40)

[matanl-starkware]

Per SNIP-40 "More Frequent Blocks", reduce the EIP-1559 block gas target from
1,500,000,000 to 1,040,000,000 L2 gas. Empirical data showed blocks were
hitting bouncer resource limits far more often than reaching the gas target;
the new target rebalances toward the actual binding capacity.

PR Summary

Medium Risk
Changes network-wide EIP-1559 block gas targeting at the v0.14.3 boundary, which can affect block fullness and base fee dynamics, though it is a spec-driven constant update with no application logic changes.

Overview
Implements SNIP-40 by lowering the orchestrator versioned constant gas_target from 1,500,000,000 to 1,040,000,000 L2 gas in orchestrator_versioned_constants_0_14_3.json, aligning the EIP-1559 target with observed bouncer-limited block capacity instead of the previous target.

The 0.14.2 → 0.14.3 versioned-constants diff regression snapshot is updated to record only this gas_target change.
