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

Nobody has claimed this yet.

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:

Add items to the cart and proceed to checkout.
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

Desktop (please complete the following information):

OS: [e.g. iOS]
Browser [e.g. chrome, safari]
Version [e.g. 22]

Smartphone (please complete the following information):

Device: [e.g. All devices]
OS: [e.g. iOS8.1]
Browser [e.g. stock browser, safari]
Version [e.g. 22]

Start at the customer app's order checkout screen and inspect how the current total is calculated and displayed. Compare the screen with the requested breakdown of item subtotal, taxes, delivery charges, discounts or vouchers, and final total. Done means every applicable component is visible and the displayed final amount is clearly explained.
