Open shell menus and panels through Hyprland global shortcuts (#13418)

Every binding that opened a menu or panel ran omarchy-menu or
omarchy-shell, which starts a qs client just to deliver one IPC call:
~60ms before the shell heard about the keypress.

The shell now registers a Hyprland global shortcut for each menu route
and panel in default/omarchy/shortcuts, and o.bind turns { menu = ... }
and { panel = ... } into hl.dsp.global for those, so a keypress spawns
nothing. A route or panel missing from the list binds through the
command as before. The default menu and panel bindings use the new form.

SUPER+SPACE opens the menu in ~31ms instead of ~94ms, measured from a
simulated keypress until the menu layer maps.
