Add is_wash field to products and support wash statistics in reports

- Introduced `is_wash` field to `products_o` for marking wash-related products.
- Updated `productsRoute` to handle `is_wash` in product creation and editing.
- Added `getTransactionsOnDateWashesCount` method in `department_daily_reports_o` for calculating wash-related transactions in reports.
- Adjusted department daily reports routes to include wash statistics output.
