fix(ui): Android soft keyboard support in terminal touch input

- summon the IME via Capacitor Keyboard.show() on tap-to-focus, since
  Android WebView only raises the keyboard for native tap-focus
- forward beforeinput text/backspace/enter to the terminal because
  Android IMEs deliver input as beforeinput with keyCode 229 keydowns,
  which ghostty-web ignores
- blur the focused terminal input and hide the keyboard before disposal
  so tearing down a focused editable mid-composition no longer wedges
  WebView touch dispatch (app froze on terminal tab close)
