 * Checks conditions to operate a gas-free flow.

 * TODO:
 * - Phase 1 (2024): Allow all passport wallets to be gas-free.
 * - Phase 2 & 3 (2025): Not all passport wallets will be gas-free.
 *   Therefore, the gas-free condition must be checked against the relayer's
 *   `im_getFeeOptions` endpoint, which should return zero for
 *   passport accounts with gas sponsorship enabled.
 *
 * Refer to the docs for more details:
