Fix keycode mapping, client disconnect, and server shutdown

- Keycodes: add +8 offset for XKB (evdev scancode + 8 = XKB keycode)
- Client: force exit on Cmd+Q/close (network thread may block)
- Server: force exit on Ctrl+C (network thread may block on accept)

Proper graceful shutdown with tokio CancellationToken deferred.
