Title: MidnightSupplyCollateralCallback

Supplies a borrower's collateral just in time when a SELL offer is taken on Midnight.

The borrower must approve this contract per collateral token and authorize it on Midnight.

Collateral is scaled to the fill and rounded down; slots that round to zero are skipped, so many small fills can supply less collateral than one full fill. maxBorrowCapacityUsage guards the resulting position health.

The offer's receiver must not be this contract; onSell reverts InvalidReceiver otherwise.
