eth_maxPriorityFeePerGas on BNB Chain

Returns a suggested EIP-1559 priority fee (miner tip) in wei. Combine with the latest block's base fee to build maxFeePerGas.

The tip half of an EIP-1559 fee. On quiet chains it's often near zero and buys nothing; on busy chains pair it with eth_feeHistory percentiles rather than a fixed constant.
