Kiosk: show all user-visible times as 12-hour AM/PM

Browse Source 
Add datetime::formatHm12h/formatTime12h and use them for the Home footer
clock, the Timezone page's local-time sample, and the log viewer
timestamps. Storage and parsing remain 24-hour HH:MM. Extends the
date-format tests with the midnight/noon edge cases.
