🛡 Reworked on "Confirm Order" popup.

Initially, we've provided "Checkout with WhatsApp" and "Checkout with OTP" both in a single layout.

Now we've created tabs to show only selected options and it's options to declutter the UI and give more clarity.

If "Checkout with WhatsApp" is enabled, it will be selected by default.

🧭 Improved Main Navigation Design

• Added a thin bar to highlight the selected navigation.

• All the icons are now colorful and bright by default.
