PR Summary

Medium Risk
Changes block fetch URLs and header fields used when syncing blocks; malformed-request fallback limits rollout risk but fee header correctness affects downstream consensus/fee logic.

Overview
Adds support for SNIP-35 proposer fee data from the Starknet feeder gateway: block fetches now request withFeeProposalInfo=true (alongside existing withFeeMarketInfo), with a temporary retry without that query param when the gateway returns MalformedRequest (pre-0.14.3 compatibility).

BlockPostV0_13_1 gains optional fee_proposal_fri; conversion to starknet_api block headers now passes it through instead of always setting None. A new block_post_0_14_3.json fixture and tests cover parsing, backward compatibility with 0.14.2 fixtures, and header propagation.
