Title: BorrowMidnightRenewalCallback

Callback that renews a borrower position from a source to the target Midnight market when that market's SELL offer is taken.

The offer's receiverIfMakerIsSeller (or receiverIfTakerIsSeller when the taker sells) must be this contract so that sellerAssets are transferred here before onSell is called; onSell reverts with InvalidReceiver otherwise.

Repays the source Midnight market debt with the sale proceeds (minus fee) and transfers collateral to the target Midnight market pro-rata to the repaid debt, all of it on the final fill.

The borrower must authorize this contract on Morpho Midnight (debt repayment and collateral transfer).

The source and target markets must list the same collateral token set: only the loan token is checked onchain, and collateral missing from the target is skipped and stays on the source, which can adversely affect either LTV. Use a single collateral, or make the target collateral set a superset of the source's.

Pre-existing positions on the target market are netted: the borrower can end up with collateral but no debt.

On small partial fills, the pro-rata collateral transfer can round to zero even though debt is migrated, temporarily increasing the target position's LTV until the position is fully migrated.
