Fix text input on kiosk: add keycodeToChar fallback for email/license pages

Browse Source 
The kiosk lacks an input method framework, so SDL2 never generates
TextInputEvent. The WiFi password page already had a keycodeToChar
fallback but email and license key pages did not — characters were
never appended to inputText. Also removes excessive debug logging
from the previous commit.
