[USABILITY] Event Registration: Update Pop-Up Messages

[cdukeUX]

Please update the pop-up messages after tapping the “Register” or “Unregister” buttons for in-app event registration. See attached images for both the current and proposed.

Current Part 1:

1. Go to an event with in-app registration set up where you are not the admin (ex. on dev, see event “Github Admin Registration” on June 29, 2024)
2. Tap the “Register” button
3. View pop-up (”Do you want to star this event?”)
4. Select “Yes”

Part 2:

4. On the same event detail screen, tap “Unregister”
5. View pop-up

Proposed Part 1 (REGISTER Pop-up):

1. ”Do you want to star this event” should be updated to “You’re registered! Would you like to add this event to [orange star icon] My Events?
2. The buttons below the new text should be “No” (blue outline) and “Yes” (orange outline)
3. Selecting “Yes” should star/favorite the event

Part 2 (UNREGISTER Pop-up):

4. The pop-up text should read “You are no longer registered for this event.”
5. The button below the text should say “OK”
6. Selecting “OK” should NOT unstar/unfavorite the event

This is implemented in version 5.2.11. There are small style differences with the proposed UI because I wanted to reuse the prompt/message styles that we already use in Calendar Events.
