enhancement: Add support for listing monitors in hyprland using hyprctl

[nikolaizombie1]

As mentioned in point 1 in this comment, the listing of monitors for hyprland needed to be independent of sww and sww-daemon. This pull request separates the querying for monitors for hyprland from sww and solely utilizes hyprctl to get the monitor names. This was done by calling hyprctl monitors and extracting the monitor names with the help of the standard library re module. A small rework for how the monitors combo-box is displayed was done to avoid duplicating the function calls in the hyprpaper backend.
