Fund a live market from the pool vault to max(required × (1 + rebalance %), initial cash, required + waiting_cash_need) (Predict's plp::rebalance_expiry_cash). Permissionless, and
takes no target. Add it AFTER a big sell's enqueue in the same PTB: the enqueue has already
added the sell's cash need to Predict's waiting total, so the rebalance funds it at once. It
takes the hot PoolVault, so add it only when a sell's cash need is above spare cash.
