subscribe in app using btc/sats user story

As a satisfied Damus user who would like to support the Damus team in app, I would like a way to "subscribe" in the Damus app with sats, so that I can support the Damus team in app maintenance & development.

acceptance criteria

1. On the Damus iOS app, I can find and click on a "subscribe" button
2. I can see preset subscription amounts: $5, $10, $20, $30, $50, $100 in both USD, and sats (see satsperusd https://bitbo.io/)
3. I can set a custom subscription amount
4. I can optionally provide my npub, or choose to donate anonymously
5. For Damus internal records it should be clear that the donation originated from website subscriptions
6. Subscribers receive ⭐️

Apple fee

In-app must yes, but you can leave the app if you want non-applepay subscriptions

Thanks, this is very handy! Apple has docs on those, but it's spread in a bunch of different places. It's nice to have a single guide from start to finish.

Sats subscription not possible in app in iOS due to Tim Apple. Migrating this to Android. damus-io/notedeck#196
