LGTM!

• I had to manually turn autofill on, I assume that's expected at this point?
• Somewhat unrelated to this PR, and I don't know if there's anything we can do about it, and it's pretty marginal given keyboard usage with iOS (I'll forgive you if you've stopped reading at this point 😅), but when I used tab to switch text fields, I didn't get the generate password prompt.

  Ah, I think that's because embedded ios-config.json file still only has the rollout at 10%; re-launching the app should pick up + apply the latest downloaded json and then would be on by default 😅
