fix: resolve indentation and import errors in backend

- Fix indentation in main.py (scheduler if/else blocks)
- Fix indentation in deps.py (credentials check)
- Fix indentation in auctions.py (filter blocks)
- Add BackgroundTasks import to admin.py
- Fix settings import in yield_domains.py (use get_settings())
