fix(mobile): apply the one-shot Ctrl on the CJK input path too

onData is not the only way keystrokes reach the PTY. With cjkInputEnabled
on, the CJK textarea owns the keyboard: onData returns early for
everything it swallows, and the focus router even redirects
terminal.focus() into the field, which is exactly where the accessory bar
sends focus after every key. So an armed modifier could neither fire NOR
be spent there — it survived until a session switch or keyboard dismissal
and then turned an innocent keystroke into a control byte, the failure
mode the whole disarm list exists to prevent.

`_handleCjkInput()` is that module's single choke point to the PTY, so
applying the modifier there covers typed characters, IME flushes, Enter,
backspace and arrows in one place, with the same policy as the onData
hook: the next single character is modified, anything longer merely
spends it. A committed CJK word therefore passes through untouched and
still clears the modifier.

Verified against a real shell session with the CJK field focused and
owning input (cjkActive true, focus in #cjkInput). Before: typing c left
a literal c in the pane, `sleep 300` kept running, and Ctrl stayed armed.
After: ^C in the pane, modifier disarmed, plain typing still literal.

Tests: 5 cases driving the real _handleCjkInput against the real bar,
both loaded into one vm scope (the bar is a const singleton, so a shared
script scope is what makes the bare reference resolve). Removing the fix
fails 3 of them.
