Enatega Customer App: There should be all the details related to the total amount on order checkout screen

### Describe the bug
Some cost components (such as taxes, delivery fees, or discounts) may be missing.
The final total may be displayed without a clear breakdown.
Users might not be sure how the total amount was calculated.
Steps to Reproduce:

1. Add items to the cart and proceed to checkout.
2. Observe whether all cost components (subtotal, taxes, delivery fee, etc.) are displayed.

### Expected behavior
The checkout screen should provide a detailed cost breakdown, including:
✅ Item subtotal
✅ Taxes (e.g., VAT, GST, Service Tax)
✅ Delivery charges (if applicable)
✅ Discounts or vouchers applied
✅ Final total amount to be paid
