48 * This hook is used to reticket points that are still on L1 but have the
49 * spawn set to L2. It first performs 3-4 L1 transactions (set keys, set
50 * management / voting proxy, and transfer).
51 *
52 * It then sets the spawn proxy using an L2 transaction.
53 *
54 * Under the hood, it wraps two existing functions:
55 * `reticketPointBetweenWallets` for L1, and `registerProxyAddress` for L2.
