Две ключевые исправления:
1. Потоковая отправка прогресса создания (SSE):
- Эндпоинт CreateWithProgress теперь отправляет Server-Sent Events
вместо возврата JSON с task_id
- Полирует статус задачи и отправляет обновления прогресса в реальном времени
- Отправляет финальное событие с данными прайслиста или ошибкой
- Фронтенд уже ожидал этого формата SSE
2. Исправление маппинга колонки lot_category:
- Добавлен явный тег column в поле Category модели PricelistItem
чтобы маппиться на колонку 'lot_category' в БД
- Категория теперь хранится как снимок в таблице pricelist_items
- Обновлены запросы репозитория для использования сохраненной
категории вместо динамических JOIN с таблицей lot
Это исправляет ошибки:
- "Создание прервано: не получен результат" (фронтенд ожидал streaming)
- "Unknown column 'category' in 'INSERT INTO'" (несоответствие схемы БД)

- Added background task manager with goroutine execution and panic recovery
- Replaced SSE streaming with background task execution for:
* Price recalculation (RecalculateAll)
* Stock import (ImportStockLog)
* Pricelist creation (CreateWithProgress)
- Implemented unified polling for task status and DB connection in frontend
- Added task indicator in top bar showing running tasks count
- Added toast notifications for task completion/error
- Tasks automatically cleaned up after 10 minutes
- Tasks show progress (0-100%) with descriptive messages
- Updated handler constructors to receive task manager
- Added API endpoints for task status (/api/tasks, /api/tasks/:id)
Fixes issue with SSE disconnection on slow connections during long-running operations
- Add CSV export functionality for pricelists with download button
- Export includes all pricelist items with proper UTF-8 encoding
- Support both warehouse and estimate pricelist sources
- Remove description column from admin pricing tables
- Show description as tooltip on row hover instead
- Improve table layout by removing redundant column

Add duplicate detection before batch insert of auto-mappings:
- Query existing partnumbers from lot_partnumbers table
- Build case-insensitive set of existing entries
- Filter out duplicates before CreateInBatches
- Also prevent duplicates within single batch
This ensures partnumber uniqueness as primary key requires.

- Add LOT creation functionality in pricing admin
- New API endpoint POST /api/admin/pricing/lots
- Modal form for creating new LOT with auto-category detection
- Creates entries in both lot and qt_lot_metadata tables
- Implement auto-save for stock mappings
- Auto-save on change for partnumber → LOT mappings
- Visual feedback (orange during save, green on success, red on error)
- Works in both main mappings table and import suggestions
- Improve stock import suggestions UI
- Remove "Причина" column from suggestions table
- Increase LOT and Partnumber column widths to 33% each
- Better visual balance in the table layout
- Disable automatic warehouse pricelist creation on stock_log import
- Import now completes at 100% after stock_log update
- Manual pricelist creation available via UI when needed
- Faster import process without auto-generation overhead
