fix: регистронезависимый поиск lot_name и удаление мёртвого кода

- SQLite-запросы по lot_name теперь используют UPPER(lot_name) IN/= для
  совместимости с легаси-данными, синхронизированными до нормализации регистра
- Удалена таблица local_components и весь связанный код синхронизации;
  источник данных для компонентов — local_pricelist_items
- Удалена функция getCategoryFromLotName из JS: категория берётся только
  из прайслиста, без инференса из имени лота
- Регистронезависимые сравнения lot_name в JS (warehouse stock set,
  addedLots, cartLots, allComponents.find, _bomLotValid)
- В support bundle добавлены: latest_pricelist_items.json, local.db,
  autocomplete_lots.json для диагностики
