feat(l1): clock page and lock screen in the splash lettering

The Home clock page draws HH:MM in the boot splash's slanted digits, with a
seconds bar, a centred date and the clock fields as columns. The lock screen
keeps the status bar, puts the big clock under it and shows unread messages
in a pill; the unlock hint appears for a few seconds after a key press on the
lit screen (not the waking one). Settings > Display > Lock clock adds a
compact look: a small clock with the date beside it and the clock fields as
rows (NodePrefs lock_compact, schema 0xC0DE0033). 12-hour time sets AM / PM
beside the digits.
