Entering PIN Code impossible because the keyboard is shown

### Steps to reproduce

i have protected the access to Element by PIN code.

sometimes (often!) entering the PIN code is impossible, because the keyboard is shown
then only the digits 123 are fully visible, 456 is half cut, 789 is invisible.

the only solution is to kill/quit Element and restart it again

### Outcome

do not show the keyboard on the PIN code screen !

### Application version

Reproduce the PIN entry problem on an iPhone 14 running iOS 17.7, using the PIN code screen in Element 1.11.28 or the preceding version. Inspect how the PIN screen presents the keyboard; done means the keyboard is not shown automatically and all PIN digits remain fully visible.
