/**
 * Intended for use with cross-channel fees (i.e. secondary channels other than
 * the asset channel).
 *
 * Given an array of `FeePendingBalance` index keys,
 * query the entries and determine if an unspent balance is present.
 *
 * @remarks
 *
 * Zero out any positive balances and write `FeeBalanceCreditReceipt`
 * entries to note that unspent fees should be credited back to the
 * end user / identity to their $GALA balance on the asset channel.
 *
 * The intended flow for cross-channel fees expects that a secondary channel operator
 * first executes this chaincode method, `settleFeeBalances` to zero out
 * unspent fee credit authorizations as needed.
 *
 * The `FeeBalanceCreditReceipt`
 * written on-chain represents a credit due in $GALA on the asset channel to
 * refund unspent, previously-authorized (burned) $GALA for cross-channel fees.
