fix(trayicon): re-apply tooltip after show() to fix empty tooltip on Windows 11 (#115)

On Windows 11, QSystemTrayIcon tooltips set before show() may not
register with the system tray backend, resulting in an empty tooltip
on hover.  Re-applying the tooltip text after the icon is visible
ensures the platform picks it up.

Fixes #112
