Make overlay panels activating so clicks are received

The session log showed active=false after every activation attempt on
macOS 26: cooperative activation is denied for LSUIElement apps, and an
inactive app's panels let clicks fall through to the windows below.
Remove .nonactivatingPanel so showing the overlay activates the app
(previous app focus is restored after capture as before).
