Отдельный репозиторий для базы, фасовки товара, ввод истории
Три правки по замечаниям.
1. База и код разъехались по разным репозиториям. Автокоммит и раньше
трогал только vault.fmdb, но лежал он в той же ветке, что и исходники,
поэтому пуш тащил всю историю программы. Теперь data/ — самостоятельный
клон food-records со своим .git, а исходники его игнорируют целиком.
При первом запуске приложение встаёт на уже существующую историю
сервера, а не заводит параллельную.
2. Фасовки товара. Пачка печенья 10 шт за 200 ₽ и та же печенька поштучно
за 30 ₽ — один товар с двумя фасовками. Остатки, себестоимость и FIFO
считаются в базовых единицах, поэтому поштучные продажи вычитаются из
купленных пачек. Размер фасовки хранится в документе слепком.
Миграция схемы 1→2 не меняет поведение уже заведённых данных.
3. Быстрый ввод продаж за период: выбор диапазона дат, строка таблицы —
отдельная продажа, ввод с клавиатуры, запись всех разом. Незнакомое имя
заводится как контрагент, повтор периода подсвечивается.
Тесты больше не имеют настроенного remote, чтобы не ходить в сеть.
