fix: keep virtual keyboard open when tapping special keys

- Use onPointerDown with preventDefault() instead of onClick
- Add onKeepFocus callback to SpecialKeysStrip and SpecialKeysPanel
- Expose focusInput via onTerminalReady in TerminalComponent
- MobileTerminalWrapper passes focus callback to keep keyboard open
