feat: screenshots answer with a thumbnail notification

All four Print binds go through hypr/scripts/shot.sh. Every capture
lands on the clipboard and posts a notification showing the picture,
with Open, Save (for clipboard captures, which wait in the runtime dir)
and Edit when satty is installed. Cancelling the region picker does
nothing.

Notification cards now load images passed as a path hint: Quickshell
routes those through the icon provider, which returned a placeholder.
