Build a gasless GBLIN payment. The vault's share token implements EIP-3009, so the holder signs an authorization and anybody can carry it on chain: the payer needs no ETH. Returns the EIP-712 message to sign (its domain is read from the token, not assumed), the calldata that carries the signed authorization, and the x402 'exact' payload for paying an HTTP endpoint in GBLIN. Use method 'receive' when paying a known recipient: only that recipient can submit it, so nobody can front-run the transfer. Use 'transfer' for an x402 facilitator, which submits on the seller's behalf. With relay: true it also prepares the fee authorization for relay_gblin_payment, for when nobody else will carry the payment. No private key is requested, held or transmitted: the signature is produced by the caller's own wallet.
