feat(appearance): steps window, icon regen, cursor out of hypr-theme

StepsWindow shows unified-desktop-theme's pending manual steps, one tab per
consumer, centred on DP-3 on the top layer with on-demand focus so it can
stay open while commands are pasted elsewhere. udt-steps writes the files
and calls the new `steps` IPC verb; indented lines become command blocks
with a copy button. The Theme tab pipes install.sh's output into it.

The icon switch now also reruns udt-accent (SDDM power icons) and
waybar-theme-udt's install.sh (taskbar theme, module icons), chained after
the gsettings write both read. Cursor changes write ~/.config/udt/cursor.lua
instead of editing hypr-theme's tracked environment.lua.

The theme notice and the Udt.qml comment claimed install.sh reloads
nothing; it reloads Hyprland, waybar, kitty and conky now.
