Batch Position Management

Under heavy loads, when PartyB is receiving a large number of requests, obtaining a Muon signature for each one and then sending them individually to the contract can slow down solver response times.

To address this, we added batch methods to the contract. These methods still require new Muon signatures, but they allow multiple positions to be opened or closed in a single transaction using one batch signature.

openPositions / fillCloseRequests 

    function openPositions(
        uint256[] memory quoteIds,
        uint256[] memory filledAmounts,
        uint256[] memory openedPrices,
        PairUpnlAndPricesSig memory upnlSig
    ) external;

    function fillCloseRequests(
        uint256[] memory quoteIds,
        uint256[] memory filledAmounts,
        uint256[] memory closedPrices,
        PairUpnlAndPricesSig memory upnlSig
    ) external;
