Fix: Исправление определения недели на границе года (ISOYEAR)

- Заменен EXTRACT(YEAR) на EXTRACT(ISOYEAR) в materialized view для корректной работы на границе года
- Обновлена миграция 001_create_schema.sql для использования ISOYEAR
- Создана миграция 006_fix_weekly_report_mv_structure.sql для исправления структуры view (LEFT JOIN)
- Добавлен endpoint /admin/recreate-mv для пересоздания materialized view
- Обновлена документация миграций в README.md
- Обновлены зависимости Go (go.mod, go.sum)
