Adds a reusable
Handler.feePayerPreflight(...)helper for server-side sponsorship flows.The helper parses and validates sender-signed Tempo transactions before fee payer signing, and can optionally run
eth_estimateGassimulation with an attached fee payer address.Handler.feePayernow reuses the same parsing path internally.This is aimed at developers who want a Rabby-like preflight step before deciding whether to sponsor or forward a transaction.
