fix(income): погашения облигаций попадают в календарь выплат
У облигаций из ленты операций не было ни даты погашения, ни номинала, а погашение строилось именно от них. moex_payouts дописывает оба поля из паспорта бумаги (только пустые). Аналитика берёт дату погашения из графика номинала, если поля нет, считает сумму по номиналу накануне, а последний шаг амортизации не учитывает дважды.
