Fix backspace in grab mode: inject KEY_BACKSPACE via uinput

Browse source 
When grab is enabled, the physical key is intercepted by evdev grab.
The engine's pop() updates the buffer but the KEY_BACKSPACE was never
injected — send_char('\x08') can't emit a keycode and fell through to
paste_string. Now backspace injects KEY_BACKSPACE press+release via
uinput directly.
