core: fix EIP-7778 block gas accounting to exclude refunds
EIP-7778 requires block-level gas accounting to exclude refunds, but receipts must continue using post-refund CumulativeGasUsed. The previous code used a single gas value for both purposes, causing: 1. Miner's header.GasUsed (post-refund) diverging from validator's expected value (pre-refund), rejecting all refund-heavy blocks. 2. Receipt root hash mismatches with other clients (e.g., Besu) since CumulativeGasUsed was incorrectly set to pre-refund gas. Fix by returning two gas values from ApplyTransactionWithEVM: - receipt: contains post-refund CumulativeGasUsed (unchanged behavior) - blockGasUsed: pre-refund gas for Amsterdam, post-refund otherwise All callers updated: state_processor, chain_makers, parallel processor, miner/worker, t8ntool, simulate, tracers. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
