[NT-627] "View rewards" when a project has ended

[ifbarrera]

📲 What

Adds "View rewards" as a menu option on the Manage/View Pledge screen when a project has ended.

🤔 Why

So that users can still view all the reward tiers on a project they backed that has ended.

🛠 How

• added the logic to return the .viewRewards option in the menu when the project has ended
• updated the logic that displays the button on the rewards carousel: it used to read "View your pledge", but now because we're coming from the View Pledge screen, it just reads "Selected"
• updated tests and screenshots

✅ Acceptance criteria

• Navigate to a project you backed that has ended. Tap "View Pledge" from the project page. On the Manage Pledge screen, tap the Menu icon on the top right. You should see "View rewards" and "Contact creator" as options. Tap "View rewards". You should be taken to the rewards carousel - all rewards that were not backed should have no CTA button, while the reward that was backed should have a CTA button that is disabled and reads "Selected".
