fix(money): update transaction data when pay token changes on deposit

The deposit total stayed stale after changing the pay token because
handleDone (which syncs requiredAssets and atomic-batch calldata) only
fired on the first prefill. Reset the one-shot latch when the prefill
drops so the full update re-runs for the new token/amount.

Also shallow-spread txParams in syncMoneyAccountDepositRequiredAssets
to avoid mutating frozen controller state (read-only 'type' error).
