List of changes proposed in this pull request

• Removed older components about the discount sub-feature of CGN;
• Refactored the CgnMerchantDiscountItem component removing the older hook that was used to show a bottom sheet with the discount details;
• Added two new screens with its navigator:
  • CgnDiscountDetailScreen: It's used to show the discount details
  • CgnDiscountCodeScreen: It's used to show the discount code if the provided discount is any type of api, staticCode or bucketCode;
• Added a new selectMerchantDiscount action used to pick the discount details when the user tap on its details;
• Added a new setMerchantDiscountCode action used to set the discount code to show in the CgnDiscountCodeScreen when the user taps on the Generate/Show discount code CTA;

N.B: Tests of these pages will follow in another PR with another jira ticket

@Hantex9 few general questions:

1. Why aren't we using the custom-tabs approach for webviews, same we did for the payment flow?
2. Can we change the height of the bottom sheet according to the actual inner content?

@Hantex9 few general questions:

1. Why aren't we using the custom-tabs approach for webviews, same we did for the payment flow?
2. Can we change the height of the bottom sheet according to the actual inner content?

1. Because CGN merchants need to inject a header into the sites opened within our app, this header ensures that the user accessed the page through our app and not through another channel. This requirement cannot be met using the "custom tab" approach.
2. Nope, that screen with the discount code inside isn't a bottom sheet, it's a modal

[Hantex9]

are there any dead translation labels? (text we do not use anymore)

Removed unused translation labels in the following commit: 61156f0

[Hantex9]

is this implemented? https://www.figma.com/design/yOoBGDr1MJpa0LY5lDUFSd/IOapp_CartaGiovaniNazionale?node-id=6102-36903&t=GUegOJgTBvvmBRMv-4

Thank you for pointing that out. Based on the comment left on Figma, it seems to be a design oversight, as with the current attributes provided by the backend, we are not able to determine when to display that banner.
