Keep universal clipboard shortcuts working in terminals

Sending the shortcut through wtype's virtual keyboard let the physically
held SUPER merge into the injected chord, so terminals saw
SUPER+CTRL+Insert instead of CTRL+Insert, and injected CTRL+V could even
trigger the SUPER+CTRL+V clipboard manager bind. Send via send_key_state
with no window target instead: explicit mods go straight to the focused
surface, layer-shell panels included.
