cmake -DWADA_HOST_BOARD=m9 compiles the M9's key path (HAS_M9_KEYBOARD: the
d-pad, the function keys, the Back ladder, the chat message walk) into the
host app on the web board, so M9 navigation runs headless with
--size 320x240 instead of only on a device. The rest stays the web board
(its caps, no SD). platform/WebM9Keyboard.cpp feeds the host keys in as the
controller's bytes.
Scripts: `key NAME [COUNT]` takes a raw byte (`key 0x81` = MSG) and a count
(several keys queued before one render, as on a busy device). The demo
backend takes WADA_DEMO_CHATTER_MS / WADA_DEMO_CHATTER_BURST so messages
arrive at known times.
UITask gates that named the board where they meant its keyboard now name
HAS_M9_KEYBOARD (keyboard backlight level, map pan, nav always on), the nav
globals and CAP_KEYPAD_NAV also take the host flavour, the M9 loop's
lock-screen service sits behind CAP_LOCK_SCREEN and the CardKB drain steps
aside for the M9 keys. Unchanged on every device build.
