fix(proposal-24): bake buffered SDK maxFeePerGas into Arbitrum retryable

Overfunding msg.value does not change the retryable ticket's gas bid: the ticket uses the explicit
maxFeePerGas argument. The estimator was baking the raw current L2 gas price (~0.02 gwei) instead of the
SDK's buffered p.maxFeePerGas (+1000%), so a rise in Arbitrum L2 gas before execution could leave the
retryable underbid and not auto-redeemed (still manually redeemable, but not the intended behaviour for a
governance action). Now bakes the buffered maxFeePerGas (220_000_000 ~ 0.22 gwei) and refreshes
maxSubmissionCost/value from a fresh estimate; value (deposit*10) already covered the buffered deposit.

estimate_arb_submission_cost.js now uses p.maxFeePerGas (not getGasPrice). Regenerated calldata.json + HTML.
