Bank statement reconciliation now automatically matches installment-based accounting entries when the system is confident they belong to the same statement line. This reduces manual reconciliation work and applies payments to installments in a consistent order.

Moves with installments should be auto reconciled if we're sure the move
is linked to the statement line.

If we are sure that the installments are linked to the statement line
then the installment with the lowest id should be reconciled first.
