admin f7810ba33d feat: duplicate detection + original URL in description
- Add original recipe URL to Mealie description (appended after blank line)
- Check for duplicate recipes on scrape (match orgURL or URL in description)
- Show warning with link to existing recipe if duplicate found
- User can still import anyway (warning only, not blocking)
