Request App Store review

We need to actively prompt users to gather more feedback.

Let's use the standard native method for requesting App Store reviews from Apple.

And make sure to follow the Ratings and review best practices.

Because Apple says:

Ask for a rating only after people have demonstrated engagement with your app or game.

We could for example trigger a request for review after:

• A user sends their first transaction.
• Viewing the 12-word mnemonic phrase
