feat: накидка по строке в таблице «Цена продажи» + минимальный CSV

Browse Source 
Sale-таблица показывает LOT/Описание/Кол-во/Накидка,%/Цена вместо Estimate/
Склад/Конкуренты/Ручная цена; итоговая цена строки = база (raw estimate или
доля от общей «Ручная цена») × (Аплифт к estimate + своя Накидка%). Экспорт
CSV этой таблицы теперь выводит только LOT;Описание;Кол-во;Цена. Buy-таблица
и массовый экспорт по проекту не затронуты — новые поля запроса опциональны
и включаются только кнопкой «Экспорт CSV» у Sale-таблицы.
