'this is just a once off' text when needing to re-set-up e2ee is confusing and incorrect

i just upgraded my iphone, and on launching element ios on the new phone, it didn't have its e2ee identity keys any more (reassuringly). however, the error that pops up saying that you have to logout/in to regenerate e2ee is confusing, as it claims this is a one-off which should be expected. it'd be better to say something like 'Lost e2ee keys; you will have to log back in to generate them'. On the plus side, it didn't break my account on my old device :)

The issue concerns the Element iOS prompt shown when end-to-end encryption keys are missing after changing phones. Start by reproducing the prompt on iOS and searching the project for its current wording; done means the message accurately explains that keys were lost and that logging in again is required to regenerate them.
