## Description

Mints `amounts[i]` to `recipients[i]` in one call. All-or-nothing: any element
revert unwinds the whole transaction. Emits `Transfer(address(0), recipients[i], amounts[i])`
per element.
Dev: Reverts with `ContractPaused(MINT)` when `MINT` is paused.
Dev: Reverts with `AccessControlUnauthorizedAccount` when the caller does not hold `MINT_ROLE`.
Dev: Reverts with `LengthMismatch` when `recipients.length != amounts.length`.
Dev: Reverts with `EmptyBatch` when either array is empty.
Dev: Reverts with `InvalidReceiver` when any `recipients[i] == address(0)`.
Dev: Reverts with `PolicyForbids(MINT_RECEIVER_POLICY, ...)` when any recipient is not authorized.
Dev: Reverts with `SupplyCapExceeded` when the cumulative mint would exceed the cap.
Param: recipients Accounts receiving the minted tokens.
Param: amounts    Per-recipient amounts, parallel to `recipients`.
