hyprland: SUPER+Right creates a new workspace past the end of a monitor

m+1/m-1 only cycle existing workspaces on the active monitor and wrap at
the edges, so SUPER+Right never created a workspace. Replace them with a
Lua helper: advancing past the last workspace on the monitor now creates
a fresh (empty) workspace there; going before the first wraps to the
monitor's last workspace.
