Enhance: Replace All now clears orders + Auto-creates categories

- Replace All option now deletes ALL sales data (orders, payments, customers, messages)
- Auto-create missing categories in text import (same as CSV import)
- Deletes in proper order: sales data → products → categories
- Ensures clean slate for complete catalog replacement
- Add formatted product import file with variant collections

Changes:
- ImportFromTextAsync: Delete sales + products when replaceAll=true
- ImportFromHumanTextAsync: Auto-create categories + delete sales data
- Regex parsing to extract category names before import
- Enhanced logging for deletion operations
