refactor: единый источник категории LOT — local_pricelist_items.lot_category

Удалён мёртвый серверный слой управления компонентами/категориями,
который дублировал источники категории LOT. В рантайме категория всегда
берётся из local_pricelist_items.lot_category (наполняется синком из
qt_pricelist_items.lot_category).

Удалено:
- repository: UnifiedRepo/DataSource, ComponentRepository, CategoryRepository
- services: старый ConfigurationService (заменён LocalConfigurationService),
  ComponentService, ComponentToLocal, ImportFromLot, ParsePartNumber
- quote.go: недостижимый online-блок (qt_categories) + componentRepo/
  pricingService/priceResolver

Сохранены живые типы: models.Category/DefaultCategories (для /api/categories),
ComponentView/ComponentListResult, CreateConfigRequest/ArticlePreviewRequest/
ConfigurationGetter/ErrConfig*.

bible-local/03-database.md: зафиксирован единственный источник категории LOT;
qt_categories/qt_lot_metadata перенесены в server-side only.
