fix(dyn-input): capture numpad 8/2 as digits, not history nav

NumLock açıkken Numpad8 / Numpad2 logical key olarak ArrowUp / ArrowDown
geliyor ama text "8" / "2" taşıyor. Klavye aboneliğinde ok/geçmiş
arm'ları bu tuşları yakaladığı için dinamik girişte 8 ve 2 yazılamıyordu.
Printable glyph üreten her tuş artık navigation arm'larından önce, text
alanı üzerinden yakalanıyor; whitespace/control üreten tuşlar (Space,
Enter, Tab) named handler'lara düşmeye devam ediyor. Gerçek ok tuşları
(text üretmez) geçmiş gezinmesini korur.
