Frontend improvements:
- Add batch processing for expense creation (3 expenses per batch)
- Implement 1.5 second delays between batches to avoid overwhelming server
- Better progress logging and user feedback during batch processing
- Handle rate limit errors gracefully with proper error categorization
Backend improvements:
- Add specific rate limiter for expense creation endpoint (50 per minute)
- More informative error messages for rate limit violations
- Separate rate limiting for expense creation vs general API usage
This prevents the HTTP 429 'Too Many Requests' errors when importing large CSV files with many individual expense records (listing fees, ads, GST entries, etc.).
Multi-layer duplicate prevention system:
- Enhanced frontend duplicate detection with tracking number, amount, and date comparison
- Added MongoDB compound index to prevent database-level duplicates
- Improved backend error handling for duplicate key violations
- Added cleanup endpoint to remove existing duplicates
- Enhanced user feedback for import operations
Frontend changes:
- Stricter duplicate detection comparing tracking number, vendor, amount, and date
- Better error handling and user feedback for duplicate scenarios
- Added 'Clean Duplicates' button to remove existing duplicates
Backend changes:
- Database compound index on reference, vendor, userId, amount, date
- Enhanced error responses with duplicate detection flags
- New POST /expenses/cleanup-duplicates endpoint
- Improved duplicate key error handling
This should eliminate the double Australia Post expense entries.
- Remove localStorage from all 4 Redux slices (products, orders, expenses, customers)
- Layout fetches all data from API on mount; adds logout button with active nav highlighting
- Wire API calls in Products, Orders, Expenses pages for all CRUD operations
- DataImport uses POST /orders/bulk for CSV upserts and API for PDF slip orders
- MissingProductsModal creates products via API
- Relax Order model: optional customerId, embedded customer, fees, printingCost on items, default paymentStatus=paid
- Relax Expense model: free-string category, add taxDeductible/vendor/reference fields
- Add printingCost to Product model
- Add POST /orders/bulk endpoint for upsert-by-orderNumber
- Raise rate limit to 1000 req/15min for bulk imports

Frontend:
- Login and Register pages wired up to API
- PrivateRoute redirects unauthenticated users to /login
- Token persisted in localStorage, restored on page load
- Axios instance automatically attaches Bearer token, redirects on 401
Backend:
- userId field added to all models (Product, Order, Customer, Expense)
- All queries scoped to authenticated user's userId
- Register/login return JWT token

- User model with bcrypt password hashing
- Register, login, logout, and /me endpoints
- authenticate middleware applied to all API routes
- JWT_SECRET configurable via environment variable
