Fix: Resolve Django settings import error and fix quick login API endpoint

Settings Refactoring Fixes:
- Add minimal LOGGING structure to base.py for multitenancy.py to extend
- Restore LOGGING import in multitenancy.py
- Add development LOGGING configuration to local.py
- This allows multitenancy.py to extend LOGGING configuration properly

Quick Login Fix:
- Update frontend .env.development to use VITE_API_URL=http://localhost:8000
- Previous configuration tried to access api.lvh.me which failed due to
  django-tenants not recognizing that hostname
- Using localhost:8000 directly bypasses subdomain routing and accesses
  the public schema where auth endpoints are available

Both fixes restore full functionality:
- Django now starts without import errors in local development
- Quick login API calls now succeed and return authentication tokens
- Frontend can authenticate users for development/testing
