treewide: refactor to better conform to previous module changes

[NotAShelf]

DONE:

• isWayland is now an internal option, set automatically if any of Wayland desktops are enabled (i.e Hyprland or Sway)
• Programs that depend on env.isWayland now depend either on meta.isWayland or the desktop env that they are tailored for (i.e Hyprland and Hyprpaper)
• use usrEnv.desktops.<name>.enable instead of haphazardly depending on env.isWayland and sys.video.enable
• move screenlockers under graphical/programs and use usrEnv.screenlock..enable toggles

TODO:

• Move sys.video to meta and enable if there's a GPU and system has at least one desktop environment enabled
