"""
Fix script: Normalize all CartOrder field names across vendor analytics_views.py
Old field names (from an older model design):
  - total          → total_amount
  - payment_status → status  (no such field; use status)
  - order_status   → status  (same unified field)
  - date           → created_at
  - buyer__email   → user__email

Also fix: VendorOrderDetailView object fields and EarningTrackerView filter fields.
