feat: qwerty on-screen keyboards for devices with a physical keyboard

Add HAS_KEYBOARD config (selected by the T-Deck board) and lay out the
on-screen keyboards qwerty to match the physical keys: the mnemonic
word-entry keyboard and the upper/lower-case passphrase keyboards.
The passphrase space key moves to the end of the middle row as qwerty
needs all ten bottom-row columns for zxcvbnm plus the control keys.
